Kustom Truck

"Great guys, always a pleasure to deal with and work with. Couldn't ask for better!"

"I wouldn’t rely on any other company for a Peterbilt wiring harness…I would be willing to bet that Mario, knows more about the anatomy and physiology, of peterbilt wiring, and electronics, than anyone I’ve ever talked to."

"Bought one of the OEM KW pyrometer kits, I couldn't get it working, even after a trip to the dealer but I called in and talked to tech support severalllllll times throughout the process, and I think Mario was his name but I can't recall for sure, they were as helpful as absolutely possible! I gave up after 3 days of fooling with the connections at the CECU and decided to call Kustom Truck to discuss sending the kit back. I ended up destroying the pyrometer probe taking it back out of the down pipe, discussed it with Pete, got it sent back and got a very fair amount refunded considering the kit was missing parts that I had damaged. I don't do much as far as wiring and stuff, but I would do business with this company again without a second thought!"

"We have used two of their harnesses now. One was for a motor swap changing from multiplexed engine to a analog input. And the other was just to replace the oem harness as price is half of oem cost. Both harnesses were plug and play with no issues. Definitely makes wiring engine swaps a breeze."

"Bought an adapter, done the engine swap. Wont start, got all the schematics from Caterpillar, traced every wire. Not totally sure why it wont start. But, wires aren't matching up from my 05 kenworth w900l to the 3406e 40 pin ecm. Called and they only have one man that has anything to do with this and he's not available."
