The wiring adapter I got with my new headunit has 2 different ground wires on it, a chassis ground and a signal ground. My headunit has one ground wire labeled as a chassis ground. On the instructions that came with the wiring adapter(from
crutchfield) it says the signal ground should be connected to the "Black" wire. I don't know if its talking about the black chassis ground wire on the wiring adapter or the black ground wire coming out of the head unit. I guess what I'm asking is whats the difference between signal ground and chassis ground and which goes where.
Thanks and I apologize for being a newb
