High quality harness and greatest customer service experience I've ever had. Answered all my questions and even gave me personal advice for my very specific situation!

I did a DL8 to DL3 conversion on my 2014 Silverado LT. Phil was on point with getting me the equipment I needed and shipped very quick. His communication was excellent and answered everything in a very professional manner. The harnesses and power fold mirror switch were of high quality and nothing short of cheap. I can't thank him enough for being my go to guy for making this conversion easy as can be. Thank you Phil

DE2 to DPN conversion. Very nice harnesses. Installation went well. Power fold would have been nice, but this is what my budget allowed at the time. Everything works except heat, but I think I'm close to a solution (this is going from basic manual DE2 to Tow). I like the added visibility, added safety with mirror directionals, and aux cargo lamps help with backing up in the dark. This was a nice upgrade for my truck.

Thank you so much for the excellent demo videos and the quality harness that functioned as expected with both sides done in less than 1 hour.
Also, awesome surprise in the box was a diode to connect in the BCM which makes the white lights function when in reverse. Of course this too came with large size color photo figures and was thoroughly explained. That took 2 minutes, maybe.

Very satisfied with the expertise of Phil, the excellent product, and the outcome is phenomenal. Love it

Phil is an awesome guy. Helped me out on a Saturday to get this done correctly. Everything works just like intended and its like my truck is new to me all over again. Thanks Phil! Keep up the good work.
