99 xj stereo wiring


New member
Guys years ago my stereo was stolen after it was upgraded.

There's a large ground wire going into the xj harness, but the stock stereo worked fine.

I don't understand how this is possible? Wheres it grounded then lol?

The new stereo has a large yellow wire intended for 12v battery direct/ constant( i dont intend to use this) and a large black wire for ground, assuming it's intended to match the stock ground.

This IS needed right??
