I have a HUGE issue. As you know the 90 onto 94 swap is almost complete. Issue comes in at the wiring harness. Through the fire wall and into the ecu or ecm. Not the three units that actually go into the computer but the other two (white one and grey one). Since I just kept the motor side of the harness on the 94 motor and the body side from the 90 it is not matching up. Is there anyone out there with a solution. My guess is I have to pull the 94 wiring harness and put the 90s on. PLEASE ~ PLEASE tell me it isnt so. 4Crawler if you are out there...... HELP!!!!!!!

Does anyone know what those two pigtails are called and/or what they are for? If I knew what to call them it would make my searches all that easier. Thanks guys.
