So I've taken a lot out of the engine bay and have a few questions about the wiring harness.

Part of the harness goes in on the passenger side and the other goes in on the driver side. The driver side harness looks okay. In fact, the only wiring on the driver side that's messed up is the wiring going to the altenator. This line goes somewhere under the engine and I'm not really sure were.

So my question is, does this connect to the driver side harness at some point? If it does then i'll need to remove that. Does that mean i'll need to take the dash off to get that line out?

The wiring harness that comes from the pasenger side firewall is all one section. It runs to the left side and then under back to the right. In order to get to all of the harness you need to pull the intake off, though I can probably be corrected on this, but thats what i had to do to my 88se

It is a separate harness. There is 3 harnesses there. The body the emissions and the charging / ground. The charging one with the alt wires and batt wires bolts to the side of the frame rails by the oil-sending unit. The body harness just pulls out from the passenger’s side and eventually pulls out of the driver’s side. The emissions harness is only from the ECU to the motor.

Okay... so the big bundle of wires coming into the engine bay from passenger side is both the Emissions and the body harness? But the body harness also comes from the bundle of wires from the driver side? Does the charging/ground go into the cabin at some point as well?

Does anyone have a picture of wiring harness lying out of the car, clearly so i can see what exactly i'm needing to replace?

No problem, I think I can see most of the harness's in the 4 pics I took. Main harness that contains teh injector wires is laying on the windshield, still hooked to teh firewall. The harness for teh left side is on the inner fender.

The charge harness does not go into the bay. Only the emissions harness goes from the passengers to the motor only. The body harness comes out main from your drivers side and wraps all the way around. balive only if you have ABS but I may be mistaken that the body harness loops back into the passengers firewall.

if you were asking about the charging wire for the alternator, i think you can run a new one from that to the main fuse or positive battery table. don't know if this helps, just my $.02
iceblue, are you saying marijuana is an unintelligent thing to do?

Look at your FSM for what and where the harness go/run. Attached is a jpg of a series four harness out of the fsm. The Blue is the Engine harness, Red the Front harness and the Emission harness is black/white (the one with the fuel injectors). The fsm's show how things run/route.

well, thats a wonderful statement, i try to think of everything that way because everything is only the way you perceive it. well i perceive it as anyone else would a cup of tea (isn't that gay?!!?!)haha. btw, i need a harness for my 88 gxl ( i know this ain't the right section).

I have a S5 vert, so i'm not certain how accurate the jpg is. One last thing, i've got the enginer harness (or emissions harness if you'd like, the one coming in from the passenger side) disconnected fully from the engine and i'm ready to pull it out. I also have it disconnected from the ECU.

Do i have to take the dash of to remove this? In other words, is this harness plugged into something else up under the dash besides the ECU?

Parastie

HA! There are two plugs just under the dash that need to be unplugged. I was just able to reach them.
