hey Kevin - yours is from a 91? Looks like the 90 has a couple potentially significant differences...considering one more attempt before I start soldering and for $100 it'll be worth a shot.

If you can post what the differences are please post for archiving

91 on left, 90 on right - 1st difference: 2 connectors on 90, only 1 on 91 (above grey/black).


90 above, 91 below - 2nd difference: 90 has larger brown connector, 91 has smaller grey connector:

still looking for a 91...holding onto the 90 just in case.

Was your original harness good before clipping it? I might consider repairing it if finding one is so difficult. Not best, but good considering supply

as far as i know, yes. i'm slowly resigning myself to the fact that i may ultimately need to splice on a good PCM connector and 60+ wires...as of now, the PCM connector on the 90 harness is the only good one i have and there are definitely some differently colored wires. haven't reviewed wiring diagrams yet...hopefully they're still out there.

I should come back to this sooner than I have. Mine is for sure from a 91. Shoot me a PM and I'll send you my phone number if you'd like to text. Easier to send pics that way.

No worries at all! DM incoming. THANKS!

There are EVTMs on ebay for both 1990 and 1991s. They'll probably run you $25 buck to get both, they would answer all the wiring difference questions.

Attached are the diagrams for 1990 and 1991. Draw your own conclusion.
