1994 YJ 4.0. I am thinking about pulling the wiring -Fusebox and all out of a 1995 4 cyl. I am assuming that all items will be compatible with my 6. So can anybody confirm? thanks

I *think* i have read that the 4 and 6 cylinder computers are the same and the 2.5 just did not come with the extra wires for the 5th and 6th cylinder injectors. But i really couldn't tell you for sure but it might be help in a google search.

I would seriously doubt that any four cylinder harness would have all the correct lengths and connectors for a six.

Go to pg 217 of the '94-'96 Parts manual. there's a difference in the harness between years, and which 4.0 and injection , ABS or not.

Nope not the same... the late 4 cyl multiport harness can be modified to run a y cyl with a y cyl computer...

95 and 94 may well be different too
