Light green is backup.
Yellow left turn
Dark green right turn
Brown taillights
Red power
Black ground
Dark blue brakes

That's seven and all that is needed. Could not activate the light blue.

I was confused. Idk why I was thinking it was backup lights.

 

[ktmoutfront]

On some years it is. I was confused.

And then I could not get the right blinker wire to activate on the test light. Spent 30 minutes trying to figure it out. Then realized I did not strip that wire.

Only thing I could find was center high mounted stop lamp?

My brain is mush right now lol. Blue on the trailer side is backup and it bypasses the surge brakes. Sorry... thinking out loud

 

[ktmoutfront]

Never thought about a center brake light.

On another note. I now have cruise control.

On fords they have an ignition feed to the trailer. Usually on its own fuse. Not sure on your Chevy.

What would a keyed hot be used for on a trailer? I've built and fix a lot of trailers, and have never seen a need for one.

Charging only while running?

Way to small. 14 gauge.

Isn't that what the "taillights" wire is doing?

It's more of a trickle charge. Our dump trailers have two deep cycle batteries that run the pump motor and they charge off an ignition hot wire in the plug.

Yep. Same thing.

Here you go. I missed that you had B+ on red already. this is for an 03 Chevy

 

[ktmoutfront]

Forgot to load these. Still more to do. With the free wheels and tires.

 

[Truckman4life]

Don't they use third brake light for if you have an in bed camper maybe?

Makes sense. I will check the 3td brake light tomorrow just so I know.

I am sure that is what it is for. Just weird that it is in the trailer harness and not part of the bed lights harness.
