Mine is in the same location as Brand X. I picked mine up at the local Peterbilt Dealer. I was at first going to get the unit that was pictured above that connects from the block out to the new receptacle, but that was very expensive. Instead I purchased the receptacle, receptacle boot, cover and gasket for about $25. I used a heavy duty 12 guage extension cord connected to the existing plug and ran it over to the driver's side where it was wired into the new receptacle. I installed a piece of stainless steel sheet metal as a backing plate on the back of the plastic part of the bumper for support. It has been installed for almost 3 years with no problems.
Definately one of the best Bomb's.
If you have any questions about the install let me know.
