So the more I find with scary previous owner (PO) wiring, the more I think I need to get an entirely new harness. Is there such a thing available for an '89 TBI truck? Or am I stuck wiring my own or adapting a universal type setup.
Things I've found that concern me:
I have thought I could just replace problems as I find them but one of my longstanding fears has been losing my truck to an electrical fire. With everything I'm finding so far, I'm thinking it may just need to be replaced.
Would a TBI wiring harness from Painless replace the injector wires, coil wires, and that wire from the starter to the alternator? I'm thinking of the type of harness you would buy if you were swapping TBI into an old carburetor truck.
I mostly rewired my '84, but a carb truck is different from a TBI truck. And it's a very time consuming process I'd rather avoid.
Any thoughts/experiences?
Things I've found that concern me:
- Spliced wire going to the coil the PO used for the tach
- Badly cracked insulation on the injector wires
- 4" of mysteriously bare wire from the starter. It's the wire that feeds back to the alternator according to the diagrams. For some reason a length of it is bare.
- Rat's nest of wiring back at the taillights; I assume some attempt to wiring in a trailer connector.
- Most of the engine wiring harness is missing the protective covering.
- Strange splice in the temp sender wire I have yet to investigate
