Custom delete Wiring
 

Ok so as the title says I'm making a "custom" wiring as in deleting all junk wires I don't need such as all the ac wires I know at least a couple of people have done this could any of you guys shine some light on what harnesses/plugs I need to chop off if u could give the harness code that could help also such as (F-51)- rec. fresh select motor ??? What ever that is lol

Before anyone ask it's a 87 fc TII

Hit the FAQ, you will find a link to wiring diagrams for the entire car.

"rec. fresh select motor" sounds like part of the HVAC system, specifically, the motor that toggles between fresh and recycled air.

Not knowing this points up a problem...you need a fairly good grasp of the harness before you can "weed out the crap" without problems. It's not hard if you approach it in sections but ultimately you'll need a good overview at least.

Yeah I get u that's why if anyone could let me know what they cut I already have a fair understanding of the diagram I'm jus kinda lazy on searching wat every single harness is I already rewired my emission harness and well the front/engine harness is next to be fixed

are you talking about a "tucked harness"? if so do a search for that

Not tucked more as jus unnessary wire removal I'm leaving only the wires that the 7 needs to function all other wires are getting removed

Then you need to define "function".

It's also worth noting that some of the wiring usually considered to be "junk/crap" can be easily repurposed to become "useful/integrated".
The AAS system for example, can be quite handy.

Point being, just because you have no current use for some circuits (to be determined after you define "functional") doesn't mean you might not in the future.

To function such as all luxury that the car comes with originally such as radio cigarette lighter glovebox light all those wires and if possible the plug code(you know like f-51) like this I could pinpoint on the fsm what it is exactly

I get u that is why I had already thought about that and was going to shorten those wires so when or if I need them I could jus crimp another wire to it but that's only on certain ones I had also thought about adding male & female connectors to the ends of the chopped wires so like that I can jus plug the missing connection back to how it was

Makes me rethink my views on circumcision...

If you haven't decided by now, I wouldn't advise it.

So you're talking about already hidden wires that you don't need? I figured you were more concerned with engine bay stuff. And clokker was probably leaning towards, what have you/do you plan on removing from the engine compartment?
I guess I'm just confused as to why youre removing wires in the first place if not for a shaved/tucked bay look.

Well that's what I'm going for since the previous owner thought it was a good idea to extend some of the wires and cut harnesses and not cut the extra wire I'll post later what I have removed so far

What are you going for?

Nice and tucked so far I deleted some of the check connector by the ign coil then by the main fuse box I got rid of some plugs there I also rewired my injectors,knock sensor and tps In the bay I'm not sure but I believe it's not much to remove but when under the dash there's so many wires that had been already cut such as the cigarette lighter and radio and for some dumb reason the center dash panel it's harness was rewired and extended but not finished

They most likely had something else installed that they took out later. Or tried to install something and it didnt work so they had to patch it back together.

Was the engine swapped that all of these things are extended? I guess you just need to figure out what is "extra."

Nope no swap in my opinion I believe he was jus playing with the harness too much

Wouldn't a painless kit be a better option?

Wats a painless kit

For a clean tucked look where should I run engine harness and front harness

dude go wireless! i'm not even kidding, the newer BMW motorcycles are wireless, apparently.

as an aside you can have the conversation with the police about why you couldn't signal for the turn because googles stock price was down that day

wtf wireless sounds like funn hahaha

I must say that my first thought upon reading this was that someone capable of doing the work wouldn't ask this question.

and that is why i suggested wireless, see we're a helpful bunch!

but just think once the car is all blueteethed, you can look at which position your recirc motor is on your phone

We live in an age of miracles.

So I jus ordered my wireless kit off eBay comming soon this summer

I realized I haven't shown my bay on how it had ended up with my ghetto rewire still got work to do but this is my progress

Wheres your oil fill tube and oil cap?

Ha! I see it

Step 1) buy non-hacked complete harness appropriate for your year car

Step 2) install said harness

Step 3) drive car and leave harness alone

I got a problem with step 1
1) no money to buy such thing I mean if u could supply me with the harness why not but most likely u won't so gotta keep working with wat I got

I am always puzzled with this very response...

Let's make a list.

1) Why would you buy a car that you absolutely have no knowledge of, expect to rewire, have no automotive wiring experience?

2) Do you own a multimeter?!

3) You have no money? Knowledge equals money. You buy a car that needs work with the knowledge to fix it or you pay someone else to do it.

4) Do you have a multimeter yet?

5) Why on earth would you purchase an iconic sports car but then not have any money to fix it? Reminds me of the guy here locally 10 years ago that won a ferrari but couldnt drive it because he couldnt afford the insurance and so it just sat in the garage.

I work as car audio installer so knowledge of multimeter and auto wiring is not a problem

Knowledge = money ??? Wat about experience = knowledge but not money

Yes I always expected to fix it myself along with everything I've done to my previous car without prior knowledge and learn during my process of my current project no I'm not an expert on the rotary engine but I rather learn and teach myself how it works if any help is given I would appreciate

car audio installer? best buy does not count... and running a power wire and some rca's is a completely different animal than rewiring an entire car.

Best buy c'mon now wires are wire some are thicker then others and some are positive and some are negative seems about the same now that I gotta look at a diagram to determine what there purpose is a lil different I'm not saying my job is easy but I should get some credit for what I do besides it's not jus sterios it's custom alarms setups and electric unlock conversions and more it's a lot with wireing can't tell me that doesn't count it's a lot of custom work required and it's all done with on the job experience on a lil shop on the streets ghetto yes pays the bills of course I'm jus lookin for suggestions and advise from anyone who has gone this path not to be judge on my knowledge seriously I could jus ask a customer what they think about my job or about my work if I wanted that

You have a point.
I've wired a few cars and have no specific training, just the desire to do it.

Here's the thing about wiring a FC- you're working with very proprietary, FC only stuff.
Like the bezel switches, which are hard to replace and must be used.
Relatively speaking, the engine harness is much simpler than the chassis wiring.

You do need to be very familiar with the whole system before you begin or it's going to get weird down the line.

Okay, I got to back him up on this. I have been a professional installer for 6 years and went to college for automotive. I specialize in security and convenience as well as tracking devices and surveillance.

I have done all 6 years at best buy. I just recently walked out of best buy due to a nutcase manager.

With that said, I know nothing of the OP's skills.

Well idk if u could tell (based on pic) but so far I have tackled the emissions harness personally I think it's not bad I have the wire coming out thru a hole behind the tb but I'm lookin for a different location to run my engine and 2front harness I might jus rewire my right headlight so it can run with my emission harness instead but I got a plug I'm not sure about a plug that's in the front I'll post pic

I've haven't found what this is for the fsm it's located in the front of the bay near all the relays there's also a blk with white wire jus hangin I'm not sure if it with it but any ideas
I'm guessing it green with orange and a blue wire anyone could confirm on wat this is for

Have you got the wiring schematic for your car yet?

The single dangling wire could be for the alarm on the hood latch, not sure what the plug is for but it's all the manual...you really shouldn't have to ask us for this info.

That connector in your hands is for the AC it plugs in about 6 inches away from the tank near the passenger headlight

And jus like that I'm set that should be the last wire I needed to figure out thanks

I do got it jus that since there are so many wires missing I second think everything unless I'm 100% I know what it is

So I haven't been able to do much but I notice that the clutch sensor had it's wires disconnected jus wondering wat does this sensor do I'm guessing it signals the ecu I'm pressing my clutch or watt

Does work with the tachk

That clutch switch is part of the starter interlock system (doesn't go to the ECU at all) and is meant to prevent the terminally clueless from starting in gear. If the clutch pedal is not depressed and the switch activated, the starter relay is dead.

It is commonly bypassed.

Kinda lost but do u mean it's like a safety feature to prevent from starting in gear??

Or is it like a check connector to find out if the relay is working

Indirectly, yes.

The system actually doesn't care if the car is in gear but it won't let the starter activate until the clutch is pushed in.
