I don't know much about mating wires or anything besides the average 12v and ground, but my greddy TT is missing the harness for the e brake and ecu hookups, so i only have the two wires coming out of the TT itself (brown & purple)for those hookups. I wanted to know with what wire would i be able to splice into these so that i can make them longer to reach my e-brake and ecu? My guess is any wire would work, but i just wanna make sure. thanks.

Just make sure the wire you use is the same gauge (thickness) and you should be fine. Also make sure the area you splice them at is covered good so they dont hit metal or each other and ground out.

cool, exactly what i wanted to hear. So just get ANY same size guage wire and make sure splices are sealed tight...thanks.
