I have an 88 Yj (4.2L) that I suspect has a bad ignition Module. Ive replaced every other damn thing that could possibly be the problem. (Wont start, erratic spark at the coil). Anyway, my question for the pros in the group is this: The ignition module for an 87 wrangler is $36.00 and a replacement for the 88 is $180. I bypassed my dead computer years ago. Reset the timing, adjusted the carb and its ran pretty good ever since. Can one simply use the 87 ignition module in lue of the 88? and if so, is there a wiring diagram somewhere online that could help me out? (the plugs are different etc.) Thanks in advance.
