What / Where is the body ground of Chev Malibu 1999?

Question

I am trying to install a rust proofing device on my car. The installation instructions says that for CT-1 [the type of unit I am installing] black wire goes to the body ground (firewall).

My question is where is the body ground. Do they mean the -ve terminal of the battery. The reason I doubt that it is not the negative terminal is bacause for another type of unit CT-2 [that I am not installing] they specifically mention that black goes to -ve terminal. So this probably mean body ground is different from -ve terminal of the battery.

Any help is greatly appreciated.

Answer 1

any place on the body will do for this one,all the body is a ground on that car,so all you have to do is tie in with any existing ground wire and that will be good enough,there's a lot of ground points on it ,any one of them will work good,for that ,good luck with it.

Answer 2

There Is No Body Ground.... .. You Drill A Small Poit Hole In Your Firewall And Krimp A Small Term. The The Wire And Screw That In The Hole You Drilled That Will Provided Your Negtive Gound Your Battery Dose The Samething... Follow Your Negtive Battery Cable I Go' Stright To Your Block Or Bodey Or Alt.

Answer 3

That would be a anywhere a screw is screwed into the metal of the body like the firewall or strut towers or negative terminal or cable of the battery if it's close. Test with a test light from the positive battery terminal to whatever screw you're going to use.

Answer 4

alot of cars have a grounding strap from the frame to the body/firewall. You can simply unscrew something that on the firewall and tie in there or drill a small hole and screw a ring connector to it.

Answer 5

body ground gose from firewall to block battery gose to block so they will all be grounded to the same they will all have contenuitty with each other
