2011 dodge 3500 7 pin trailer connector manual#

it was a 14v model with a dead battery, so I gutted a battery and ran 12V wire into it. 98 Chevy Silverado 3500 Cummin On Strong 12v Cummins NV4500.

It is better to just use the factory plug, and not cut into the harness. I had a truck catch fire because someone cut in a plug like that. Use 1 for the light strip, use the other for a trailer, etc. I run a power drill off my 7-pin to raise and lower the jacks. kevinc2004 said: Buy a 1 plug in, 2 tails out. OTOH, have full time power back there can be useful for running utility lamp, air compressor, etc if you build a 7 prong plug to go into it. We have an excellent wiring diagram on our website, I will provide you a link so you can look at it. You might be able to insert a relay inline merely by tapping into it with the fuse terminals. When wiring a trailer connector, it is best to wire by function, as wire colors can vary. I'd probably just pull the plug at night when stopping. OTOH, leaving it in play also provides the benefit of an overnight charge to the truck if connected with the converter powered up, provided that the additional load on the converter charge doesn't pop the 12VDC fuse. You could trace the harness and insert a relay inline with the coil triggered off an acc circuit somewhere. In my 2008 grand chero one had to reprogram the BCM to fire that relay to get power back there, or else it was a dead circuit, so the daimler/dodge family at some point had it switched. I believe it is the middle pin, not sure.

So I looked in the manual under fuse diagram and could not locate a named position to activate it. Every factory tow connector I've known fed that terminal through a relay. The trailer dealer checked the 7 pin plug on the truck and said I would need to put a fuse in the fuse box to get it to power the lights.
