So i have a 87 TII, previous owner had a haltec in it when he took everything out, he kinda did a hack job of it so im having to put everything back together.

This plug is located on the right side of the steering column its a 6 pin plug, Im assuming it has something to do with the EGI, would make the most sense to me, and im pretty sure this is the plug i used to yank out to keep the motor from getting fuel in the event someone tried to jack my car.

The current plug connected to the harness had 3 wires clipped right at the back of the plug so its unrepairable. So i bought this plug from a fellow member to replace it.



The colors from Top left to right side is.
brown/blue-Empty- and 2 black/brown(maybe yellow)

Bottom row
2 BLue/brown(yellow)-Black/white/Yellow stripes-Black and white

I started soldering some wires and finally got to this mess and am trying to figure out where all this crap goes. For instance I can locate 1 blue/brown(yellow) wire but not the pair.

I dont know if this plug came off another turbo II loom, It could be a NA plug. BUt i was told it would work from another member. Not sure if i need to cap one of these wires in the pairs off, Or if both need to be used.

IF anyone has pictures of this plug on their car that would help greatly.

I dont wanna do this wrong, throw a motor in the car, have it not start and Have a mess to find out what is wrong with it ect ect ect. And as you can see in the pictures i dont really have room for error on the plug, there not much length to work with.

Any help is greatly appreciated!!!!

Buddy thats the fuel pump relay switch. Is the plug by the bottom part of your right leg on the columns sturcture? If so that the pump relay.

^ Tie goes to the one with the pic!

Goes to the Circuit Opening relay.

Well it was dangling there So i dunno what it was attatched to But the only other Plug on teh right side of the column is a 4 pin plug.

Look for the wires missing the plug

Satch in that thread you posted There is a 6 pin plug, that looks VERY close to the one i have. However It doesnt have any pins that have 2 wires coming out of it. Any idea why? Do i need to use both?

Brown wire goes to fuel check connector and the AFM.

Blue wires go to the fuel pump.

Black/White wire next to Blue wires goes to 15 amp Engine fuse in the interior fuse box.

Black/White wire at the bottom right of your pic goes to the ECU, pin 3B.

Solid Black wires goes to a constant ground.

Sweet so . Should i splice the ends of the Dual wires and solder them up to the matching single wire? Or is there a reason for two?

satch

In both the NA and Turbo Circuit Opening relay there would be one Blue wire but the wire eventually splits into two Blue wires before it mates with the Rear harness. The wires coming out of the relay are part of the Front harness so when the Blue wires mate with the Rear harness it is done at connector FR-02. The Rear harness has two Blue wires so there needs to be two Blue wires in the Front harness. In your example the split occurs right at the relay instead of after but before the Rear harness. There is nothing wrong as long as both Blue wires have voltage on them when it is deemed necessary.

Why do you have two constant ground wires is beyond me. If one ground does its job then one is good enough.

Thanks satch, Ill give it another go tommarow when i have a new bulb for my Work light, I broke it ~! Ill try and get more pictures as well

meximan

Ok got some more pictures with some better light. This is a picture of the current harness. As you can see every pin has its own single wire and not two, like my replacement.

Found the matching Blue and red wire, and black and white wire. Im thinking that i can splice the TWO wires on the new plug and solder them to teh single matching wire and shouldnt have any problems. If theres a split later down the wire I wouldnt think that this would affect it.

Last day off to get some work done. Any helps apprecaited~!

Not sure what you are asking but ask away. Are you asking if the Blue/Red wire you found is the one that should be connected to the Blue wire(s) in the plug and so on?

meximan

iTrader: (37)

No pretty much just asking IF It's safe to assume that i can connect the two blue/red wires to the single thats been cut. and same for the black/white. Seems like i have one extra wire of both.

satch

iTrader: (1)

First thing is are you certain that the cut Blue wire that you found goes to the fuel pump. If you are certain of this then there is no problem. With regards to the cut B/W wire you found, there are two of those at the plug so you need to make sure the one you found is connected to the proper B/W wire in the plug.

hmm checkted the top of the fuel pump assembly. 3 connections. One white/black that used to be spliced i already fixed that bad boy. One Blue. One red. Is this what you meant by it splitting? Im gonna go check the ecu, right now.

meximan

iTrader: (37)

LOL just realized im retarted Different harnesses haha.

satch

iTrader: (1)

I made a bit of mistake as your car is an S4 turbo and in that case the Blue wire from the Circuit Opening relay goes to the Fuel pump relay and resistor before going to the fuel pump itself. In this case the Blue wire splits into two wires before it arrives at this relay. From the relay comes two Blue wires which eventually combine back to one after the wires connect to the connector that joins the front and rear harness. That is, on the rear side of the harness the two wires are reduced to one wire. (connector FR-02).

Ok one what should be last question/problem. These are on the driver side kick panel. Two what i think would be ground wires. One looks like it was placed their , The other im not sure if it was used or needed.


And this green wire i think was hooked up to the haltech. REmove it?


Thanks for all your help satch This is helping me out alot

The pic with the Green wire looks like it's coming from the Cruise control unit but I can't tell without more info. There is the plug at the bottom of the unit and then a Green colored wire comes out of that plug and then appears to go to the red clip. Can you verify what the exact coolr of the wire coming out of the white plug at the bottom of the Cruise control unit is. Is it solid Green or Green with a stripe? I'll include a pic of the diagram but I assumed the wire was solid Green so give it a look over.

The wire that its connected to is Green with a red stripe

satch

iTrader: (1)

That makes more sense. On the left side of the red clip the G/R wire enters the red clip and on the right side of the red clip the G/R comes out of it along with another wire. Is this accurate? If it is then it looks like the G/R wire , which goes to the Speed sensor in the gauge cluster, was tapped into to run an aftermarket gauge. This is my guess and this might explain one of the Black wires as it probably was the ground for the aftermarket gauge.

AHHH that would make sense. I dont know if he ran a tach though i know he had boost/temp stuff though. I actually still have the Pods. But that does make sense! So These are proboblly ok to leave alone as well~! SWEET~!

Satch ur a good man. thanks for all the help! Funny I can tear apart anything and put it back together but when it comes to wiring Im dumber than a mother effer lol.

You wouldnt happen to know how to hook up a SAFC now would u hahaha
