I was in the process of eliminating all kinds of junk in the car, and I removed maybe 10 lbs worth of junk wiring and whatever crap (even found a bottle of unknown fluid, the label is all washed out and the bottle Smells funky, I don't even wanna know what's in it)

while removing the junk alarm that one of the previous owners installed (it was a garbage install and wires are 1/2 hacked up and some of them are not even tape up)

and I wonder what these 2 wires are for. One from the Ignition switch and the other one came from the other side of the ignition wiring.



This one is Grey/Red I assume, It came from the ignition switch. it's connected to the garbage alarm(now cut off) and I wonder where is this connecting to? cuz it doesn't seem like it's connecting to anywhere.



This wire is on the other side of the wires for the ignition switch (after the connector)

I think it's black, could it be ground ?

I tried to find the wiring diagram in FSM but cant' seem to find it? if someone can tell me what those 2 wires do that will be great. if not please point me to the right section/page of the fsm so I can look it up. Thanks !

The first pic could actually be a Black/Red wire that has faded some. On an S5 there is a B/R wire coming from the starting circuit which then runs to the Heater/AC system and in particular it goes to the Ignition Relay that is a part of that system.

Found in section G-2b in the S5 wiring diagrams.

well, originally it was connected to one of the alarm's module that looks like a relay. Its not factory so I cut it off. (you can tell by the yellow connector that they cut/installed)

There is another Black/Red wire I think. Let me double check.

Don't think it's the wire, I ran downstairs to snap another pic



I'm holding the *I think* the Red/Black wire

but the one that has been cut is so much thicker, that should be used for something like Starter. but I can't find anything to plug/connect it to.

There are two other diagrams which shows a B/R wire coming from the Ignition circuit feeding the fan and Cruise Control. In this case the B/R wire feeds a Blue wire. The B/R wire runs through the 15 amp Wiper fuse so if pulling this fuse cuts power to the Blue wire then you know what it is for. And please don't run down stairs.

hmmmm ok. I probably gonna replace the ignition assembly soon cuz the lock is not working that well. I know lube probably works but it's 20 something yr old, replace might be a better idea.

but before that happens Im gonna try to fix this.

Oh do you know where the wire goes at the 2nd picture of the first post ? It's not blue it looks like a black wire. but it's same size as the cut off wire on the ignition side. Could it be the "blue" wire you are talking about?

HAILERS2

A PURE BLACK wire feeds the igntion switch the power so the switch can do something useful in life.

The pure black wire originates in the engine bay from a connector near the engine bay fuse box.This PURE BLACK wire is also spliced into the cable that comes from the alternator and cable that feeds the starter........the last time I looked. Page Z-24 of the series five FSM wiring shows what I just wrote.

When I see a large BLACK/RED wire I always think of the wire that feeds the starter on a series FIVE car and also feeds the circuit opening relay to turn the fuel pump on during the Start sequence. Same diagram as mentioned above.

Let me dig that part up ... I must be blind, how do I miss it. let me see.

nycgps

iTrader: (4)

so let me get this straight.

That Black wire from the Front wiring harness, supposed to "connect" to the Ignition wiring is that correct?

but seriously, the only "open wire" is the Black(grey?)Red wire that's left "open", so Does that mean I can just "connect them both" and it will be good?

Before I cut the garbage alarm off, both of them were connected into the same relay. I was thinking it's some sort of starter cut relay.

Oh ****, I just remember I bought a used Front Harness with fuse and everything from ebay a while ago, lemme just dig that wire up and look at it ...

nycgps

iTrader: (4)

Ok, I just dig that whole front wiring harness outa my stack of 20 boxes, it's a perfect wire with no mods to it (unlike mine, which obviously got hacked up by some morons)

if I did look at the right spot, that black wire should be Black/Blue, and has a Black 1 pin connector(obvious) on it. it's cut on my car (thx to the idiot who did this). and I think it's supposed to connect to the one on the Ignition ...

Not to confuse you but the Black/Blue wire runs to the Starter Cut Relay from the Ignition Switch.

And you have a plug on the Front harness that has two wires where one is B/W while the other is Black. The Black one comes from the Main fuse and powers the Ignition Switch. The B/W wire powers the IG1 fuses at the interior fusee box. And then the two wire plug w/the Blue wire and the B/R wire are for the Accessory fuses and IG2 fuses respectively. The plug w/the smaller wires is for the ignition key light and the key in the ignition reminder beeper.

hmmmm. Maybe I was looking at the wrong wire ?

I'm gonna compare the wiring tomorrow (day light), hmm, maybe I should just Pull the whole wiring out and put this unhack version in. jesus. but I think I gotta take out the dash for that, not sure if I wanna do that >_<

satch

The Black/Blue wire should be in its own plug that connects to the Ignition Switch. So you have a plug w/one wire, two plugs w/two wires and the plug w/four small wires or so all connecting to the Ignition Switch.

nycgps

iTrader: (4)

So you mean there should be 4 plugs on the ignition switch right ? but I think I only have 3.



Ok, one of the plug is obviously MIA on my Ignition switch wiring I think that's the starter cut relay switch, correct ?



I think I'm missing this "plug" from the Front Harness, and I assume that's the one that connects to the plug on the Ignition wiring that's missing ?

I'm going to reinstall another more "advance" alarm ... Just need to double check before I connect them, Sparks are not fun to watch

The 2nd pic in your hand is the Front harness that plugs into the Ignition Switch pigtail. It has the three main plugs necessary. Plug w/the B/L wire, plug w/the solid Black and B/W wires, plug w/the B/R and Blue wires.

nycgps

iTrader: (4)

That's the part that connects to the ignition switch am I correct?

so both of those cut off wires (ignition switch and front harness) in my car is part of the starter cut relay. I will connect it to the new alarm I'm gonna install. hope it doesn't blow the car up

satch

The Black wire from the Front harness goes to the White/Red wire from the pigtail. So the B/W wire of the Front harness must go to B/Y of the pigtail. Then the Blue goes to Blue so the B/R goes to B/W. And the remaining wire from the ignition pigtail goes to B/L.

In the first two pics the B/R would go to the Black/Blue wire. They appear to be separated in these pics because of the introduction of an aftermarket alarm or some other reason.

I just tried the car

if I leave the 2 "cut off wires" hanging, I can't start the car

Connect them, car starts

and I check power only flows from the ignition side when I turn the key to Ign. so I guess that's the starter power wire.

Gonna follow the rest to finish the Alarm install tomorrow.

Thanks guys !

Yeah, the single wire plug is for the starting circuit, mates the B/R wire to the B/L which you happened not to have, and it normally goes to the Starter Cut Relay.

Just got 1 more question, is it true that I can't get the doors to lock/unlock With aftermarket alarm WITHOUT some sort of actuators installed at the door lock ?

The car originally came with some actuators installed, but the install were so crappy it was hanging in the door panel with just 2 screws that's about to come off, so I took it out. worst is it can only lock, NOT unlock, wtf.

is buying new actuators(or little motor) my only choice to get the doors lock/unlock with an aftermarket alarm ?

^I would not know.

You helped me a lot ! I gotta say if u come NYC anytime, hit me up I buy u beer




Anybody know if I need something to control the door lock/unlock for aftermarket alarm?
