Just picked up a 09 Tahoe 6.2L LTZ
Looking to install my prodigy P3 brake controller.
My 2000 came with a FACTORY harness that was very easy to connect to the brake controller then plugged right in to a factory plug under the dash area.

Looked through the manual on the 09 dont see anything to give guidence on how to wire in.

Thanks
Dennis

 

google this question, I found a PDF on it a while back for a 08 install, should be similar...

what kind of MPG does your 6.2L get?

I've been averaging 17-18 for a whole tank in the 5.3L

I got the factory brake controler option.

 

These two links should get you going even though they are for the trucks same info applies. Note that the wires are there just hard to find and bundled up and have a white tag on them with no connector and "should" be above the e-brake somewhere.

Thanks for the links
I did a google search earlier and fond similiar.

As for the MPG. I was averaging 17-18. At one point Iwas doing 65 in a construction zone for about 50 miles. It displayed 19. Then when I was back up to 75+ it fell to 17.5.
The last 4 hours I was driving pretty good. My gas pedal leg/knee was killing me.
It displayed 17.4 when I pulled into the garage.
