Just curious since I see a 1993 complete unit for sale but I want to put one it a 1989. Will the harness work or is it not worth the hassle?
Thanks!

The harness will not be plug and play. 87-89 are interchangeable in your body. The chassis/dash harness plugs will be different.
OK Thank you!

I actually had the same issue only reversed. I got a complete setup for an 89 and had to buy a harness for my 93. So I have an 89 harness if you are interested in it. I would make you a good a deal. It does not have the supplemental harness.
I will send you a PM. Thanks

Does anyone know what a new ProM harness for coil on plug that goes in a 1989 would cost? I don't see the harness listed on their website, assuming it just comes with the kit.
Thanks

If you go into the page for the harness, select your year then it asks if you want COP. COP is an additional 100, so a new harness would cost $1000.
OK thanks!
