I need help hooking up my trans temp guage , I can't wire up this darn thing I am lost on the wireing stuff if anyone can help what I need to know is what color is the wire for the lights and a switched source for the guage side of things .
find the merry christmas thread in the CTD faq at the top of the forum, follow it and download the FSM for your truck. then you can open up the wiring diagram page and find which wires you need for power for the lights. I'll be doing the same thing in the near future as I finally have some "free" time to finish the guage install.
