yj and xj wiring harnes is virtualy the same the only differance is i had to change two ends on a couple plugs and wire in the two more cylinders, and that was it . it fired right up and like i said it ran great for a few months with no issues and its my only vehical so i drive it every day. i dont have a autovalue here in medicine hat so thats not an option.
I agree with BlackYJ ...There must be a part store in good ol' MH...it is a fair size town .Crappy tire might chanrge you for it though. Try to find a place they sell part but don't have any garage bay... NAPA, Part Source ?
Most of these places have OBDII readers. You can borrow them if you leave your credit card # with them. They do that because they want you to buy the part you need at their business after. Make sense...
