Step 1--buy yourself a Haynes manual and turn to the Wiring Diagrams section. (You can print diagrams out from Pelican's website, or from the PDF manuals available somehwere around here, but Haynes is pretty convenient and is less than $20--well worth it!)

First pic: The ring terminals go on the battery (+) clamp. The connector on the left goes on the relay board; can't see if it's the 12-pin connector at the right-rear or the 14-pin connector on the front of the board. If the latter, it's part of the main wiring harness for the whole car. Talk to Aaaaahndy about reinstalling the main harness.

Pic 2: Unknown, looks aftermarket to me but I'm not certain on that.

Pic 3: Fuel injection wiring harness. Looks like it's for an L-jet 1.8 motor. The plug at the far end plugs into the ECU (the "brain") and the other plugs go into various parts of the injection system.

Pic 4: Main harness, possibly the rear trunk end of it.

Pic 5: Main harness; I'm thinking that the branches toward the right side of the pic are where the harness splits up after exiting the center tunnel and going up to the top side of the engine shelf?

Pics 6-10: More main harness. It runs on top of the center tunnel, and has branches that run off to various parts. Up under the dash is a lot of wiring, and I think it goes into the front compartment over on the left side and branches again...

Umm, I think I've hit the end of my knowledge here. Aaaaahndy?
