ok so i got my shift master today from TS and the install looked pretty simple, 4 little wires. i just cant find the harness they are talking about to tie into. i think i found the right one but i really dont know what the pressure actuator looks like. if this is the right harness i found, it is a pain in the @$$ to get to and unplug. any help as to what i need to be looking for would be really helpfull!!
