Pacbrake PRXB Installed
 

Finished installing a Pacbrake PRXB direct-mount on the '07 today. Did a little running around afterward to get some first impressions and I am VERY impressed. Just 2 wires plugged into the ECM integrates it seamlessly with the transmission control. I found myself letting off the throttle way too early everywhere I stopped. Seems like it's running in tow-haul all the time now. Very nice setup - high quality switch and solenoid. Install was probably a 5 on the 1-to-10 difficulty scale, so just about anyone should be able to accomplish it, no problem. I deviated from the instructions a little by mounting the control relay inside under the dash and tapping my switched 12V from a source in there.

If you are considering one, I'd highly recommend it. Looking forward to seeing how it helps cold warm-up next time I have to drive it to work on a cold morning.
