Anyone who's ever been screwed by a bad ground before, and learned from it!
Or learned it indirectly, from others' experiences. Let that be all of us.

He's not wrong. Car wiring only worked because it (used to be) pretty darned
insensitive.

Not even close. The power feed to the relay is HUGE, but 99% of all that
current goes back out through the GP's. Only a dribble is used by the relay

Same as what's there, of course.
But, given that grounding is done in clusters, if one is bad perhaps so are
others.
So, track down the existing ground and fix it.

I would guess the ground wire is only grounding the small electronics in
the relay so the wire
I may have missed it, but did you confirm there's actually power at the
relay? In other words, put a meter between the (supposed) 12V feed and a
ground point such as the engine or negative battery terminal. I don't

I don't recall what year/model this is regarding but the ground points in my
car are where the brown wires attach to the chassis. I'd try removing and
cleaning any in the vicinity of the relay. They are all probably similarly
oxidized, if one is bad the others are probably not far behind.

Does it really matter? I think I would add a new ground to something

either leave your temporary fix in place permanently, or track down the
original wiring until you find the connection to ground.

So I’m back to it. It seems like the relay has no ground. I attached a test

problematic. Does anyone know where, on the body of the car, the

The cover of the 5/6 pin connector is just clipped on, it is removable.
N.B. The cover keeps the connector pins and wires in place, make sure to

I believe the 2 silver boxes are the GPR and the CC Amp. IIRC, the
CC Amp
is attached to the steering column while the GPR is not. (I hope

The other easy way to tell is look for the one with wires
on it that can take 60A of current. (The CC amp does not
have this.)
