I appreciate the reply but these pics give me very little frame of reference. Can't tell where the mounting location is.

That is on the drivers side frame rail inside the rear wheel well splash guard.

I've always wondered about this...are there any other good reasons to mount the BAP back there that I'm missing besides "it stays cooler than the engine bay" and "my plug-n-play harness was designed that way"? My knowledge of basic electronics tells me that if you're trying to transmit a large amount of power over a distance, it's more efficient to do it at a higher voltage. It would make more sense to me to mount the BAP up front, and reduce the loss across the long wire to the pump by running it at the BAP voltage (17-21V) instead of the alternator voltage (13-14V). If engine bay heat is a concern, the area behind the driver's side front wheel well splash guard seems like a good option, since hotwire kits run the fuel pump power feed down there anyway. Then again, maybe the difference is really small and I'm just overthinking it. I'm a digital electronics guy, don't do much with power electronics, but I can try to run the numbers and see what I come up with.
