87 to 89 conversion

CanadianBak'inSupra · 08-14-2010, 06:25 PM

as far as i know there should be little differences between the 2.
and really the wiring is strait forward, each plug onnly has one place to go and only 1 other plug will mate with it...

easier than you think.

Quite different actually. Different engine harness, different dash harness and all of the lighting connectors are different but the wiring and internal clips are all the same IIRC.

oh wow, didnt know.
but either way every clip can only go into its mate clip.
thanks for clearing that up!

i think he means every plug, as they all semm to be diffrent either by shape or colour with corresponding male and female ends. I think thats it, correct me if im wrong though. So im sure the wirring is quite diffrent now, i am tearing everything out of the 87 to put in the 89 chassis. What a job this will be. Any ideas on what may plug and play? Heater box? or any of that stuff?

I was hopping some items may mesh between years but so far it doesnt look like it.
Thanks

ok i get that,duh lol. I was looking at the tail light connecters and I can plug my 89 light in to the 87 harness. Do they work fine like that or do the pins feed power diffrently between years? Its a ton of work to pull all the wirring and change them over, maybe ill just have to go out to where the 89 is parked and start looking around. Thought maybe someone had more experience, in this area. thanks again though.its starting to rack my brain a bit

if your tail lights plug in fine check your fuses in both cars, should be the same, so i imagine they would be fine.

its a massive harness its pretty funny
