86 to 88 engine wiring harness
this is a continuation of a post coming from a similar question on an 89 wiring harness. I have an 86 coupe and have found an almost complete 88 engine wiring harness that is in really nice shape whereas my 86 is toast. I have been working on them side by side and have come up with a few differences and hence a few questions.
#1 just above the battery there are two relays, one for the fuel pump and according to the shop manual one for the trans overdrive. the connectors are different on the 86 than the 88. question is if there is any difference in the relays themselves. If not I can just buy new 88 relays and plug them in and use them in place of the 86 ones.
#2 the 88 harness that I bought had the harness lead down to the auto trans cut off but some of the wires were left. most of the wire colors match up and there is the same number of wires, but there is a yellow and blue wire in the 88 that are not in the 86. the blue may be a ground as the 4 prong connector on the 86 shows a cut wire sticking out of that color. the only wire on the 86 that is left is a brown with a white stripe. does anybody know if using this wire with the yellow will cause problems.
#3 the last issue is that on the 86 there are two connectors coming off what appear to be the right side and on the 88 there is only one connector with only 4 wires, wheres the 86 has one connector with 4 wires and one with 2 wires. they appear to go to the ac/heater box and may be different in that my 86 with two connectors has c86 electronic ac and the 88 with only one connector may have had manual ac. any help in how to change or modify this harness to work will be greatly appreciated.

the 86 has a black corrugated tape band and it looks like it had white writing at one time, but it is gone. the 88 has a clear tape with the numbers 7672 with kwo below it and 7672 with what looks like kwj below that. hope this helps. thanks

The fuel pump and (if you have a manual trans) overdrive relays are next to the windshield wiper motor.
