Re: No power to 12V constant pin

[ QUOTE ]
Jeff,

I replaced the relay with a jumper to get a constant 12 volt feed to the "+" terminal of the 7 pin plug. I made the jumper from a piece of heavy guage wire with spade terminals on each end. I used a test light to determine where to plug it in. This is a pretty simple mod to get a constant 12V to the rear of the truck.
Hope this helps...

Dan

The reason Ford uses the relay is to keep someone from leaving something on in the trailer/camper and draining your batteries. If you hard wire it, you can end up with dead battries [img]/ubbthreads/images/graemlins/blush.gif[/img] if you are not real careful. If the band trailer is the only aplication you have that pulls current from that pin you are probably ok but if you have other trailers/campers with a 12 charge/acc connection you may get yourself in trouble with always hot.
