bumpytruck Posted April 27, 2010 Share Posted April 27, 2010 Hi, I have a 1980 DM686.My back-up alarm was working and it has now stopped. I jumped it out in the rear and the alarm and back up light are working. The wiring seems fine as I traced it up to the front of the truck.However I cannot seem to find were it goes into the transmission.The truck has the two shifters one for hi-lo-r and the other for 1-5.Were shouild I be looking to find out were my problem is?Is there a switch on the trans or inside the trans?

Lmackattack Posted April 27, 2010 Share Posted April 27, 2010 If I recall its on the driver side of the box? I think the back up alarm and light work off the same switch.. I dont have either on my trucks but have hooked up one years ago on a 6 speed. Its all done from the outside of the gear box....
