Just a wag, check the ground.

 

I did, it was connected to the frame right next to the gauge.

 

Some pics from the install today! got my brackets made and spacers for them. everthing fit perfectly the first time too (a first for me ) Unfortunately, I dont think I will be able to fit an intercooler in there without some rearranging because of my plow mount. I may pull my A/C out since i never use it anyway... who knows.
