Starter Relay Wiring - Ground Wire Question

My 1988 4.2L wrangler received a new starter relay. The new relay had a wire terminal labeled "ground" (lower right terminal).

When I removed the old starter relay, this terminal ("ground") wire went to a multi-wire connector under the Jeep, near the tranmission and toward the back. I was wondering if this is a ground wire, or should I just make a new ground wire for this terminal. Could use some advice on this... Is this the usual connection for the ground terminal on the starter relay ?

that ground on the relay goes to the multi-pin connector that deals with backup lamps and/or neutral safety switch depending on what transmission.

For 4.2L auto it goes to the neutral safety switch so that you can only start in P or N.

with a 4.2L and manual tranny that wire is just ends up connected to other ground wires.


So if you have manual it's just a ground wire. Feel free to connect it to a better ground location.

You can never have too many ground points.

On my old chevy, I found out that under some loads the body was floating about 1V above the engine ground. Fixed that and headlights and accessories worked much better.
