I picked up the 68 and got the motor and tranny in. Im having trouble hooking the starter up because it is different than the 75. It is a 1 wire alternator and the 75 was a three. I hooked the battery to the big post on the starter. Now there are 5 other wires in that area. 1 red, 2 brown, 1 yellow, 1 purple(may be brown I cant tell) I have HEI so I dont need the yellow wire. But I tried every combonation of those wires I could think of and I get nothing. Can anyone shed some light on this for me?
