Hi ,

Sorry , in fact I'm just catching the train ... , I'm not the one that initiated the subjet but with the same problem!!! And so far you're answer is the only one simple and clear that I've found all over the net... , so in my case my car is an 85 trans-am that has seen it's LG4 swaped for old school 355 carb so the Tranny is still it's original TH700 and I need the lock=up running without the ECM , and you're the only one mentioning those wires color that I have wich are purple , blue and the third one black/tan. So I've hooked the blue and black.tan together et the purple to 12V key brake switch. Test drive is weird seems that the tranny is locking one each gear from first to OD.. , ANY IDEA WOULD BE HIGHLYYYY APPERCIATED !!
Thanks lot!!!
