On your lock up you can take the plug off the doner car, there will be a pink or purple A term, light blue B term, tan/blk D term you will need the brake switch also the A term gets voltage from the brake switch, the D term is ground side of solinoid which can be hooked to a ground and trans will lock up in 2nd gear or you can take and hook the D term wire and the B term wire
together which is the fourth gear switch and converter will lock up in fourth.
Piece of cake and you do not even have to take the pan off.
