fuel pump relay in my 94 t4r v6 at is bad. toyota wants $80 for it. seeing as the truck still runs im not worried about replacing it. however with the relay out the truck wont go into 4x4. so what i want to do is figure out which of the 5 wires will complete the 4x4 circuit so i can put a switch in and engage the locking hubs that way. any ideas? any one with access to wiring diagrams?
