s13 chassis harness issues and differences

[xDRFTurR1D3x]

Really need a good condition chassis harness for my 93 coupe. Power windows. And HUD. Need everything including both fuse boxes. The wiring on my current harness, below the passenger fuse box had the plugs smashed. So I spliced everything together (white power wires) etc. Well I guess some are switched 12v and some are constant. Well since they are all constant 12v it pulls too much voltage when attempting to start the car and voltage drops to 11.5-12.5 volts and won't kick over just click. Starters good everythings been tested over and over or replaced. I found a harness from a hatch that I'm told will need some minor rewiring? Is there anything I can do to my current harness? What's the difference between a hatch and coupe chassis harness. What exactly needs to be rewired and why? Will I be able to use my HUD? Appreciate the replys and now back to even MOREE researching. Thanks guys

Alrighty so found that HUD isnt harness specific, it just requires the correct gauge cluster. SO can anyone speak up and let me know if theres gonna be an issue if i use a 90 hatch chassis harness in my 93 coupe?

On the HUD Subject, I was just playing with one last night. The chassis harness is the same HUD/Non-HUD, you just need the correct sub harness and correct cluster.

Awesome! Now I just need people to send me myparts I payed for or have wiring specialties fix mine if this doesn't come through but prayin they do!

Real quick is there any reason I can't use a hatch chassis harness on a coupe? Everythings the same till u hit the B pillar. Please reply with your input! The harness will be shipping soon! Lol

Tails lights, defrost, 3rd brake light. You can convert it all, but it's difficult. A lot easier to just get the right harness.

Please define difficult . LOL I rewired by S2 RB25 engine harness into my 98. Like actucally depinning and repinning plugs. Not splicing in plugs and soldering etc like some people get lazy and do. So would it be a simple case of depinning my coupe harness plugs and repinning them into their correct spots on the hatch harness? I consider that pretty easy and simple. Much simpler than getting the soldering iron out and taking the time to solder and shrink wrap each wire. Appreciate the replies guys keepem coming
