Hello All.

I have a 1992 wrangler which had a 2.5/ax5 in it. I bought a late 1990 4.0/auto and built a stroker. The engine harness from the 90 looks like it will just plug into the firewall connector but I am being told there are different pin configurations. I pulled up wiring schematics from the web but cannot tell of the pin block configuration. Any ideas?

Thx, Don
