Chassis ground on hotwire

are you talking about the one thats part of the connection to the pump, or the upgrade thing they send you, the part that connects to the pump, we put mine on the bottom part of the trunk.
iam talking about the hotwire cable. There is a wire labled chassis ground and its attached to the 30amp relay, Iam not talking about the tank ground. Its the other one right next to that one.
The chassis ground mounts onto the nut and bolt that hold the front of the strap on along with the relay, just clean off the mounting point to make sure it makes a good ground
