Sorry, I’m installing the fass system and using the empty slot in the ignition plug I think it’s a molex connector . Do not know what size pin.

what is the wire connection  that you use for the unused “key on” power terminal 

Thank You all for the info, I thought the pick up tub would be ok. There you go a salesman trying to sell you something you don’t need.

I have a 07 monaco diplomat 400hp Cummins. I want to install fass fuel system. Dealer said I need 1/2 inch pick up tub,  does any one know what size pick up tub is in the tank
