The Brown Wire goes to the threaded Post on the Sender and the ground wire goes to one of the sender mounting bolts??? There is nothing mentioning this in either the Shop or Assembly Manuals | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | yes, brown to sender terminal - I don't think the sender originally had an actual ground wire, but adding one from a sender mount screw to the cab wall or floor makes having a good ground a sure thing instead of counting on the tank and straps

Thanks for the reply, thats the conclusion I came up with to. I did install new mounting pads for the gas tank and will have a separate grounding wire going to the sending unit.
