Brake Controller Battery Hookup
I thought I read in the manual I have to connect a wire under the dash to enable the power to the factory brake controller?
If I have the factory brake controller in my 09 tahoe, do I still have to do that? We put new axles on my boat trailer this winter, I haven't wired the trailer yet (just wanted to get the axles on, wiring + lights this spring) when its NOT 20 degrees outside... Once I have the trailer all wired up, 7 pin, do I just connect it, or do I have to pop the hood and hook up that wire? seems stupid GM wouldn't just connect that wire, what lawyer came up w/that? thanks! |

I've got the trailer brake controller but haven't read about it yet. I did notice a wire w/ a ring terminal on it taped to the underhood harness next to the fuse box. I did wonder about what it was for.

I didn't know they offered a factory controller. I would think that if it came with one it would be wired. I installed one on my 06 silverado and had to install the factory harness that was provided with the tow package, when I installed one in my 07 Escalade the wiring was there and it needed to be connected to the power supply under the hood.

I will look when I get to it this summer i guess... I still need to wire the brakes on the trailer as well... thanks.

power
which is for charging the battery on the brake system, correct? which is required when towing a trailer w/electric brakes... so why do they leave the stupid thing unpluged?

One less thing to short out...
