Installed relay for my Airdog Raptor Lift Pump

[noserider]

I added the relay to my raptor pump. It's now getting power directly from the alternator. It appears the raptor is happier getting power directly from the alternator and using the ECM to trip the relay. I saw an additional increase of 2 psi from the pump making no adjustments to it. I'm now showing 17-18 psi at idle, 15 at cruise and 13-14 at WOT. It would appear the Raptor being a stronger pump was not getting enough amps from the ECM to be at full potential. I'm definitely glad I installed the relay to protect the ECM from a heavy load.

Good move. Looking to do this for my AirDog as well. Heard that current draw on these pumps can take out the ECM. Not what I want.
