Need wiring diagram for a Supreme Industries truck box
Supreme Corporation or Supreme Industries made this 16 foot dry van box to go on a two-ton chassis. I'm looking for a wiring diagram or schematic since there are several plugs under the box and numerous wires. All I want to do is get the running lights working and an inside overhead work light some juice.
Many thanks for any advice or a pointer to online information.
Sounds like a job for test light and multimeter and some wire checking. Not sure there is much to the wiring on a body like that, based on what they show on their site. You might contact them if need be:
Thanks for the reply. There are more than a dozen wires terminating at connectors at the rear bottom center of the box which just seemed like an excessive number to me, and a pain to sort through in order to find the few I want. The Corporation's website is singularly uninformative, so I'll try calling them and see whether they can send me something.
At least three automotive-type connectors, each with 4 to 6 wires and it was so dirty and dark under there I couldn't tell any colors. None of them appeared to be correctly terminated as if for a trailer.
My old truck hasn't got the original wiring at the back so I've never seen what it should look like.
