    Thanks… just what was needed
    Vehicle had someone remove radio and cut the harness… had to find a similar 22 pin plug from salvaged vehicle and then make 3 wires up and reconnect new plug…

    Had a missing ground wire… thanks

    Hey guys, I just picked up a factory sub for my ’03 wrangler. It has an 8 pin connector (2 rows x 4 pins each) and the RCA audio inputs. Would anybody out there happen to know the pin out on that amp so I can make a harness? Thanks a lot everyone. Keep on Jeepin’ on!
