Where are you guys mounting these things, and the window switch/tps too? Do you guys mount these things in the engine bay or in the cabin and just route the wires through the gromet to the engine?

 

ttt for the night

 

I mounted mine in the engine bay. Relay right next to the front framerail there just ahead of the battery. My digital window/wot controller I put on a clear spot on the inner fender on the passanger side, just behind the TCS unit.
