Mark from Michigan - AHU / Vanagon harness

I received the wiring harness last week and all I can say is WOW. This thing is quite a sight to behold. I am really impressed with your craftsmanship and attention to detail with these harnesses. I can't wait to get it all wired up to the TDI engine!

Kyle from British Columbia - ALH / Samurai harness

I was impressed with the wiring harness and the turn around time to get it done. I liked the simplicity of your system and that is was easy to install.

Bob from California - BEW / Jeep harness

Thanks I got it today! Definitely looks great! Beautiful. That upgrade to the relays, attention to wiring, terminals.. is superior to anything I've seen, ever! Totally impressed....

Tyler from New York - ALH / Toyota harness

Shoutout for David Marshall at Fast Forward Automotive. Received my ALH harness today, and it sure looks amazing. Looks better than a factory engineered VW harness. Also a modified harness diagram, labeling all circuits in harness like a factory manual. Couldn’t be happier!!!
