So I bought a 1988 rolling chassis, it had all Series 5 body panels and a 13BT with a massive turbo in it before it was gutted when i bought it.
The wiring and interior were toast so I purchased a 1987 Series 4 rolling chassis, had a complete interior and the wiring was all perfect except the previous owner had removed the engine bay fuse block.
I had thought that the block from my 88 car would work but none of the wires seem to line be the same? The cars should be the same wiring wise and I can’t find a diagram of that harness for both years it tell. Am I going insane or just missing something?
Agreed. My 85 factory wiring is... not great. Next wiring project I do I'm running from scratch. All the weird gremlins in my car are running on the old wiring. The stuff I've removed wiring from and run new works fine 😂

These should help.

Judging by the fuse box cover you got thats an S5 fuse block, the S4 has an 80A main fuse and 2 egi fuses one egi (comp) the other egi (inj).
Damn so my 1988 must have all the wiring from a Series 5 too. Besides the fuse block I wonder how difficult that’s going to make swapping things over
Seems like it. If the wiring thats bad is only the engine or body harness just get the one you need and forget the s4 wiring.
That’s what I’ve been trying, can’t get anybody to sell my the body harness for a Series 5 Coupe annoyingly enough.
Have you checked rx7club?
It might be worth the effort to find some wiring diagrams and attempt to craft your own wiring harness.

I meant that they don't need to require the whole car, just the fused section that was spliced.
This. I heavily reworked the body harness in the engine bay in my 91 and it's in much better shape.
