Now that the weather is cooperating, I spent a couple hours this afternoon fully removing the wire harnesses from the engine bay. The plan is to remove the stuff I no longer need and add new leads for things like race, engine bay, and interior lighting.
This post is more so I can reference these pictures when it’s time to put it all back together. (Click on any image for the blurry, full-sized Blackberry picture.)
This one looks like a main power feed for the interior fuse panel. Same side as the fuses.
The back of the interior fuse panel.
Not quite sure what this is (yet). Yellow connector reminds me of the SRS (airbag) harness on newer vehicles, but GVR4s did not have airbags, so…
This guy (relay) had its own mounting block. Not sure what it does (yet).
This group of relays is tucked up under the dash above the fuse panel. Not sure what it does yet.
The mess I was working with. [195] is JSB, so it was easy to sit sort of under the car at times, but the roll cage support (left) made it kind of difficult to get to some of the hardware without contorting around it. (Kent was right. I should have fully stripped the shell prior to the cage install.) You’re looking at the driver’s side foot well, notice the shifter cable top right.
Great success! This is the harness which runs through the A-pillar and DF wheel well and snakes under the radiator core support (note the fat section with the orange zip ties) to just in front of the PF strut turret. You can see the engine bay fuse/relay block. If you look above the fuse box, in that tangled mess right there, the white bits are the strain relief where it goes through the A-pillar, and you can see the positive battery terminal.
I am considering relocating this fuse/relay block into the cabin on the co-driver side, as well as re-routing the section that usually goes under the radiator across the back of the engine bay.
AC condenser unit (black box) and HVAC fan (white box). In the foreground is the Techflex CleanCut I will be using to re-wrap the harness.
Removing the AC condenser core and HVAC fan unit opened up a HUGE amount of space, providing access to the bolted strain relief on the second engine bay harness (not pictured), which passes through the hole just left of center in this picture.
Since this car no longer has AC or ABS, I’m toying with the idea of re-using the fuse/relay locations in this block for the pencil, driving, and fog rally lights going on the car one day.
A look under the cover of the engine bay fuse/relay block. Note the six round relays at left. I might replace the top three.
I’ve got to do a little research, but this size relay will also plug into the locations currently filled with the round, silver jobbers. P/N MB183865

This wiring project is just getting underway. I’d really like to build a harness board to lay everything out during the process. We’ll see if I can make that happen. My cordless drill walked off long ago, and I’m not very handy with lumber.
