Yes it does. I'm sure you can come up with a different mounting solution if you really tried.
I need to investigate the wiring as mine recently decided to stage a mutiny. Day 3 and counting.

I now have a cover on the way (well, Monday it will be), so that's handled, but I still have to wire it up.
I have a plug that mates to the motor, now I need to open up the b-pillar and find the chassis harness plug and see what that looks like.

Despite the frigid conditions, I installed the dome light and H4 headlights yesterday.
Both work, so that's good.
Whether the lights will be a big improvement remains to be seen, I sure hope so.

******* Broncos...

OK, need some help here...although I suspect I'm screwed.

I cannot find the chassis harness plug for the wiper motor.
I've peeled back both the upper and lower pillar plastic and the connector doesn't seem to be present.

The FSM shows it right next to the lead for the hatch heating element and indeed, there is a two lead cable guide in the chassis but it only holds the heater wire, there is no two wire plug for the wiper.

I thought all harnesses were fully optioned out but I can't find a hookup for the washer pump either...the whole circuit seems to be MIA.

I've searched the harness in both directions from the theoretical location and can't find an unused plug taped away and don't see the B/R and LG/Y in the harness bundle (but I can't see all the wires without delooming and I ain't doing that today...).

This is becoming way too much work.

On the passenger side of the car, at the front end of the hatch strut, do you see how the wire for the cargo light goes through a black grommet? (Assuming the S5's have this light, I don't really know) That's how the wiring goes for the rear wiper on the drivers side strut (At least, on my S4 with a stock rear wiper). The plug should be within 6" of that grommet behind the plastic panel IIRC. Maybe it's tucked beneath the side carpet? I can take a picture this evening on my S4 parts shell if you would like.

Yes, I see the blind plug where the wiring should pass through but no plug.

A pic would be goodest.

for once i thought to look at mine, which conveniently is an S5 with a rear wiper.... my hand is blue because its cold, not because i'm a smurf

hopefully that works, there is a white harness guide it branches off of on the driver side. there is one big black/white wire, and a teeny greenish one. 2 pin connector

Yup, pretty much as I thought it would look.
I have that same cable/hose stay on my chassis but it only holds the defroster wire, there is no unused plug for the wiper (and no cut wires/evidence of tampering).

It is interesting to see how the washer hose is set up there though.
I'll file that away for the future...

Now comes the hard part.

I have to assume that, despite my previous understanding (which I have parroted as "advice" many times), there is such a thing as a "decontented" chassis harness.
I'd noted before, as I worked in the bay, that there were no connectors for AAS or ABS present in the harness and now I've found further factory pruning in the cabin.
If I were ambitious- and it wasn't painfully frigid- I'd check behind the passenger b-pillar plastic to see if there is a plug for the optional strut lamp.
I'm guessing there isn't.

Now that I think about it, I don't believe I have the power "follow lock" on the passenger door either (or I do and it's broken).

Is the S5 GTU really a stripper as well as being de-optioned?
Did the GTUs come with a similarly pruned harness, because it makes no sense for Mazda to have a special harness for just one model (and the base model at that).

Anyway, although the two circuits (motor and washer) are dead simple, I haven't a clue where the factory wiring ends in this harness. Is the switch actually connected, or the fuse?
How far up the harness must I go to find the wires I need?

j9fd3s

my friend has a GTUs we did a power window swap in, and it was missing the wire that powers the window circuit. i'm not sure what else, but i would imagine GTU/GTUs would be the same.

my car is a 91, and well actually since its got the washer tube it must have had the rear wiper too,

clokker

iTrader: (2)

Well, I guess I need to start at the switch (remember, the original GTU wiper/combo switch was bad and was replaced with a switch that has the rear wiper circuit) and see if the dash harness even has the wires for the wiper.
If so, I assume I'll be in the footwell to see where the wires have terminated (probably at a connector, I'd wager) and how difficult it will be to add them.

Using the stock switch is the preferred option but it will depend on the wiring.

The second approach would be to make an entirely standalone wiper/washer harness.
The battery is in the bins, so power is available.
I see no reason I couldn't use one of my spare wiper switches to run the system...the problem is where to locate the switch. If possible, I'd like to use the main wiper switch because it has variable intermittent and mist functions but it's not an easily packaged unit due to size. The stock rear switch may be more practical.

An unexpected roadblock so late in the project, what a pain.
All of this would have been so much more easily dealt with had I thought to look when the whole interior was out.
And it was warm.
Collectively known now as "the good old days".

I'm running into similar problems trying to swap my base model door panels for some turbo 2 ones that have the lights and storage bin thing. No harness for the plugs can be found, and so they sit waiting until it warms up enough for me to tear apart the dash and see just how far back I need to go, assuming there's connectors at all and they didn't use a completely new harness for each model...

chart from the parts fish. 89-90,

the easy one, is the LS diff WITH ABS, as that is a turbo, with the giveaway FC18 part number

next is the GTUs, LS diff, without ABS, its the only S5 so equipped.

the GXL, is the FC04, as the AAS, rear wiper and power every all come together.

that leaves the FC01 for the GTU, which must not have the wiper wire, but probably has the power window wire as its an option, i think.

with my friends GTUs, the power wire from the power window fuse to the door connector is missing, so we will have to add it, at some point, i would imagine you're in the same boat.

91-92 has no chart, its just turbo (FC18), MT(FC04) and AT (FC09)

j9fd3s

iTrader: (3)

if you have an 91-92, you should only need the door harnesses. if you have the 89-90, you will be screwed if its a GTUs, with a GTU you should just need the door harnesses

If it ain't one thing it's another...

Began exploring the wiper wiring and peripherally noticed that the dome light wasn't on...WTF?
I'd just fixed that a few days ago, new bulb and all.
After removal I still couldn't see anything wrong till pure chance revealed that the wire to one of the bulb cradles had come loose.
The little POS was riveted on and the rivet just fell apart...how the hell does that happen?
I bodged it back together and we'll see how it holds up.

As for the wiper circuit...
Looking at the schematic it appeared that connector X-26 was the one I needed and naturally, I couldn't find it.
I'll admit being somewhat halfhearted in my efforts because as soon as I origamied my way into the footwell all I could think was how much bloody easier this would be if the dash was out.
And that is NOT happening today or anytime soon.

I'm loathe to bodge into the stock harness (I could probably tap in on the wiper switch harness right at the bezel for instance) because I want to preserve it intact for version two of my wiring project (scheduled for the hazy future), so I'm now looking at a standalone harness that bypasses the Mazda wiring completely.

I'm taking a conceptualizing visit to the junkyard, hope it's not too cold.

You have till Monday. I saw on the news it was supposed to be near 50 like today for the next couple of days... But we will see I guess

Mission accepted, sir.
Booyah!

The yard was good to clokker today, he found his Precioussss.


This switch was harvested from a 1990 Subaru Loyale (I saw an identical one in a 1991 Legacy). It fits the currently blanked space in the center console where the fog light switch would go.
It is a fully featured switch: lights, wash and mist but all I'm using is ON/OFF.

Keeping this simple makes it a two wire circuit...I think I can manage by Monday.

I am actively ignoring the WASH function for now, primarily because I do not have, nor would I use, the colostomy bag reservoir that Mazda settled for.
A reservoir is on my list of things I'll look for in the yard...something useful will turn up eventually.

Bonus points to whomever can identify the purpose of the two little brackets (they are not Mazda pieces...).

cluosborne

The brackets look like the type to prevent the floormat from slipping forward. Mazda 3 uses brackets like that.

clokker

iTrader: (2)

Exactly right.

Too easy, that one.

cluosborne

In fairness, that feature caught my eye when I was reading Edmunds long-term review of the Mazda 3 Skyactiv, and I thought those would be handy for my RX7 too, so I kept a pic.

j9fd3s

iTrader: (3)

just an FYI the Rx8 floormat bracket* is like that too but its just flat.


*Mazda is usually 10 years ahead, in this case the 88-92 626's had a floormat recall

These were from a Honda Accord but once I started looking, they were everywhere.
I'd meant to grab some many a time but these were just laying there, I didn't have to unbolt them, so my innate sloth was overcome and they were mine.
Just installed 'em as a point of fact.

Started stripping out the interior bits- mainly the driver side bin and the center console- to begin the wiring.
Need to get some supplies first though.

Justin1992

iTrader: (1)

You installed those studs to prevent the floor mats from slipping? Mind if we have a pic? I don't have a drivers floormat but i do have a passenger one, and every time i clean the car i get pissed off because the floor mat is pushed, crumpled and crammed up into the damn dash and rather than the dirt being all on the floor mat, it's on my carpet. Makes cleaning a PITA, and i don't exactly want the floor mat to get ruined by having that happen to it, either. I've been thinking of how i can hold it in place but the extent of my solutions thought up (Albeit not tried) has been a bit of velcro, which isn't exactly ideal.

Don't mind at all:





The following pics may be NSFW:




Interior carnage, always good for page views...

Why, you might ask, are you tearing apart so far back in the corner?
Well, it occurred to me that the (currently) unused power antenna plug had a perfectly good switched/fused power lead in it, much easier to access than even the battery. It's even rated for 10A, same as the rear wiper.

I obtained some heatshrink and wire and was all ready to go when a cake baking emergency arose and delayed my progress.
Altitude can be a bitch, kids.

clokker

And it's done:






The PARK function works but there's no intermittent or WASH.

I made the standalone harness mimic the stocker in that the connector from the motor to the chassis is in exactly the same spot as factory. When I convert to the stock switch the window harness will remain intact/untouched.
All the wiring is plug-n-play and can be removed without leaving a trace.

Lot of work for a function I'll rarely use.
