towe001 Posted August 7, 2009 Report Posted August 7, 2009 If the car in question is the ae82, you'll find a few plugs down near where the wiper motor lives. One of the plugs has two connections in it, thats for being able to time(ignition) the motor. From memory it cancels all settings like advance etc and just sets it to the base ignition timing. If its not done you wont be able to correctly set the timing. Apart from that i didn't really think the 4age had a diagnostic port. But then again it has been a fair while since i had one... One good idea - grab yourself a few different service/repair manuals on the car in question. Quote

Bigports have the cluster of open-ended connectors near the wiper motor, pretty sure smallports have the single moulded diagnostic port connector Quote

Trev Posted August 8, 2009 Report Posted August 8, 2009 Get pics and post them up, Pretty sure we are all confused right now. As far as I can figure out, This is a 4age in a KE55 so the loom has most probably been modified. Quote
