I replaced the engine in my '85 GS with a new, non-destroyed one, and I'm trying to put everything back together. I've got most all the mechanical bits hooked back up, but now I need to get the wiring sorted.

I didn't so much remove as neglect to install the rat's nest, so the usual DIYs and FAQs assume everything's already plugged in and tell you what to remove. Unfortunately that doesn't help me much, as I need to know what I need to hook back up and what connections I'm safe to remove completely.

Help.

Plugs A & B: I don't even remember unplugging these guys, and I have no idea what is supposed to hook up there. Any ideas? That's the clutch master in the background, for reference.



Here's two close-ups for the wire colors. A:



B:



It's fairly obvious what this guy is, but it doesn't seem to plug into anywhere, if that makes sense. The harness coming from the passenger side of the bay doesn't reach. C:



Sorry it's a tad blurry, but, uh, what? D:



I don't know what's going on here. E:



This is just cut, or the connection broke off. Any ideas? F:



G:



H:



And then these guys, I:



Any help is appreciated. Thanks in advance.

 

The FSM wiring diagram is your friend. I would start there.

 

Take a close look at the plugs, you'll find a number of them never plugged into anything. That looks to be the case for A&B. Does C come off of the oil pan? If so, the forward sender is oil level, the rear one is the temp sensor for the hot start. D may go to the temp sender under the oil filter, E/F, not sure about. G may go to the carb. In the I group, all green plugs are for diagnostics.

That should get you started. Hit the wiring diagram for the rest.

 

None of the colors seem to match up with the FSM, that's part of my problem. But thanks for the help with the others.

 

I did a clean up of the wire harness and the harness from the pass side is basically composed of rats nest wires entirely all except for 3-4 wires. At least my car was. lol

 

Over time the wires fade and discolor. Scrape the wire coating to see the true colors. It's all there in the wiring diagram. Just takes time and patience to figure it out.

 

B is the Power Steering control Solenoid K-08.

 

If you peel back some the tape to see the color

 

lots of them are unused beacuse the Japanese version had turbo wireing also so some could be from that is the car canadian KPH insted of MPH on the speedo?

 

could be a thought sorry didnt mean to sound like i was sure that was it.

 

I've got them all sorted out except for E, the yellow wire with no connector on it currently, and D. It's a single-pole connector, but it's T'd into the oil pressure sensor. WTF?

 

the single bullit connector on D looks to be the connector for the coolant temp sender. but based on the length it could be the connector for the a/c compressor

 

What would that have to do with oil pressure, though?

 

neither should be tied into the oil pressure sender wiring.

 

Then you understand my confusion.
