So I have a 88 mj that I bought a 4.6 stroker an ax15 and a 231 tcase the jeep was originally a 2.5 manual 2wd it’s 4x4 now but previous owner chopped the harness at firewall what is my best option wiring harness wise I have a full harness from a 99 same year as motor but is it comparable with the interior harness? And my second question is what are you guys doing for Ecus and can you buy a ecu and harness kit?
