I have a question for anyone who has swapped a manual tranny in place of an auto. I am working on a 88 Blazer that came equipped with a 700R4 and have installed a NV4500 in its place. I need to know about some wiring going to the Park/Nuetral switch on the bottom of the column. I originally thought if I disconnected it the truck wouldn't start, but it will. So I need to know what this wiring is for. It is a two wire connector and the wires are Orange w/white stripe and Black w/ white stripe. If there is a GM Mechanic who knows or anyone else, please let me know. I am baffled. Thanks Layne I may be slow, but I sure am fat!
