The harness has save a bunch of time on stripping cars and getting me into the money three times this year
I have ran carbs for a very long time till I was introduced to Lmmf wiring harness an tuned ecm an it changed everything for me in the derby world
Has taken me to the end a few times now deff worth it
I’ve bought 2 of these and won 1 in a raffle these things arr great to me helped with making the builds easy being able to strip all wire out of the car and not having to worry about not cutting wires and while running there are limited amount of wire to worry about if you shut off in a derby
Car was literally hot enough to boil an egg and kept running.
Ryan Sealock has the best products known to the derby world if you want the best buy the best his customer service his 12/10 you cant beat the product or the service you get with it
I ran it through out the county fair season and had zero issues out of took it to blizzard bash got rolled on my top picked the box up off the floor and fired the car right back up thanks to the switchbox and harness of lmmf
Amazing product, easy setup! Any questions, Ryan takes the time to explain everything.
All I can say is this product definitely made me party and it won me the derby and mad dog
Best in the business. Bought my first setup about 2 years ago and have bought multiple since and have no complaints! Ryan’s the man
Ryan is a great dude and is always there to help get your motor running top notch no matter the situation!
Hot switch works great! Helped me get to second without it there would have been no check to cash!
