I am currently in the process of doing an auto to 5 speed swap in my 1991 extra cab. The auto is out and all the other stuff for the swap is in the truck or ready to be, except for bypassing the nuetral safety/ park switch. I have tried jumping the two larger ( black and black w/ white stripe) wires and I just here a click not the starter turning. Anyone know if these are the right wires or am I missing something here..... are there other wires to deal with? If someone could tell me the colors of the wires on a 91 auto trans and what they are for that would help.
