This so far has been one of the best forums I’ve been on. I’m learning a lot with the help of y’all!

my other favorite forum has been Turbo Diesel Register with lots of good people there who I’ve learned a lot from for my 1st Generation Dodge Cummins D-350.
by chance where can I get a part number for that brake/interlock switch. Nearby we gave Napa, Carquest, Advance & AutoZone parts stores. Dealers are a last resort for me as they are good for being idiots & ridiculous prices
