Bought this to convert my 1984 Olds to a manual lock up, installed it in the 4th gear port on right hand side and put a switch on the console, works like a charm.

Best used when connecting lockup torque converter without computer control. This switch passes current when the transmission shifts to 4th gear on a 2004R and 700R4
