1G Wire harness help

[aaronhenderson54]

Hey guys looking for tips and advice for how to figure out what wire is what on a hacked up harness. Checking continuity from connector to said wire ? Any advice or tips would be appreciated here's some pictures of the mess

Identifying the connector and the wire colors is how I usually start. Then track it down in the FSM diagrams.

The link above is a solid reference if you had a 2G but for a 90 you want https://www.dsmtuners.com/threads/the-1990-engine-control-wiring-harness.412841/ and https://www.dsmtuners.com/threads/the-1990-engine-compartment-wiring-harness.473792/

Oh shoot thanks not sure what happened there I will try again

I'll have to do my best with the wire color I had pictures but I guess they didn't upload so I will try again most are broke or just have spade type push on connectors but I guess seeing the wire and color pattern and going from there

Im having trouble uploading photos from my phone I'll have to try my computer

Once you can get the pics loaded up we can provide more pointed advice. Honestly, unless that previous owner completely depinned and rewired everything, you probably still have remnants of the original wiring attached to the connectors. I'll wait for pics before going deeper. But, yeah... butchered wiring, especially if done duct tape style by Darryl and his other brother Darryl, is never fun.

Haha thanks for the reply it's not full darryl but some hacked and a couple I have an idea what they are I'm having trouble uploading pictures I'll have to try my computer

Okay hopefully this works this is just vague pictures I can get closer ones or whatever if anyone can help I know the one wire bunch with the grommet was the o2 sensor as I de pinned it my self. Also the one wire with the piece of orange grommet was one of the wires to the alternator.

Let me know if you can help with any of those or any suggestions

It's good that most of that looks like factory wiring. Hopefully someone will be able to recognice the positions and wire colors and know off the bat what some of those wires are.

Me - I'd have to go to the FSM and research the wiring diagrams for what everything is.

That's your best bet honestly. Start with the diagrams that show you where the various components and connectors are located. Use that info to narrow down the diagrams you look through. Time consuming, but 100% proof positive (provided the wiring is unmolested factory).

Okay very good I'll do that and start from there. Thank you
