Neg side of battery and ground same thing?

I am installing a Spal fan controller and the instructions say to connect the large black wire directly to the negative side of the battery. If I connect this wire to a sperate ground is that the same as connecting to the negative side of the battery. Is there really a difference? My battery is in the truck and I prefer not to run a wire to the back. For reference, see page 4 of the instructions.

Re: Neg side of battery and ground same thing?

Well, all grounds lead to the neg battery post. The difference sometimes can be the quality of the connection/ground since poor grounds affect performance. You can use a multi-meter to test continuity and measure the resistance... The less resistance, obviously, the better ... I would be surprised if you just cannot find a good, clean ground point and go with that... Monitor that the wires are not getting overly hot when running the fan...that would be a sign of high resistance
