Trailer connection help

[Rosson03]

What does the dealer need to do to get my trailer lights Goin, I check book here's what I found

 

[Sparksalot]

Do you have the 7 pin socket at the bumper already? What are you trying to do?

 

[Rosson03]

Yes I have the Socket, there no power there

 

[wjburken]

Have you checked the fuses?

 

[Rosson03]

Hooking up to a trailer

 

[Rosson03]

What Fuze is it please I already left the truck at friends

Yes I have the Socket, there no power there

Oh that’s simple. There is a coiled up wire taped to the side of some wire harness below the master cylinder. The wire needs to be connected to one of the terminals on the front side of the under hood fuse panel.

The coiled wire is red. The terminal toward the fender is the constant hot. The other is for connection to a trailer brake control.

I thought the wires you are talking about are only for trailer brakes and aux power to the trailer. I thought the trailer lights were already active.

In the fuse box under the hood:
Fuse 3 & 6 are your Trailer Turn/Stop lamps
Fuse 10 is your Trailer back up lamp
Fuse 24 is your Trailer Park lamps

It would be worth it to double check the wires going into the rear of the socket by the hitch as well as maybe take some emery cloth or fine sand paper and clean off any possible corrosion on the connectors in the socket. You have a 13 year old vehicle so who knows what condition your wires are in.

 

[Rosson03]

Yes, the lights should be active.

Well that's the fun part, I got to move a switch them around, u want to help code it for me, I posed my wire mess

 

[Sparksalot]

It’d be way easier to rewire your trailer to standard configuration.

If you need electric trailer brakes.

mine doesn’t have any due to weight, but I definitely wanted the power.

I don't have a trailer that has electric brakes,
So I'm pretty dumb do I find these wires under dash and run them down or do I just connect the 2 under hood I'm good,
Thanks

You have to connect the brake control wiring at all if you don’t need it. Just do the power.
