2.2L VTECH, 2 DOOR MANUAL TRANS

PRETTY SPECIFIC ISSUE/ISSUES WHEN STARTING CAR, THE RADIO WILL COME ON AND TELL ME THAT WIRING IS WRONG TO CHECK WIRING IF I SHUT IT OFF AT THE HEAD UNIT AND TURN IT RIGHT BACK ON IT WORKS GREAT, WHEN RADIO COMES ON YOU CAN HEAR FEED BACK IN PASSENGER DOOR, THE DOOR SENSOR FOR PASSENGER SIDE DOOR COMES ON DIM, AND IF YOU LEAVE DOME LIGHT ON, IN MIDDLE WHERE LIGHT ONLY COMES ON WHEN DOOR IS OPEN, WHILE DRIVING THE DOME LIGHT WILL LIGHT UP WITH THE BEAT OF THE MUSIC.. I REMOVED AN AFTER MARKET ALARM WHEN I BOUGHT THIS AND THERE ARE 2 WIRES HANGING UNDER DASH ON THE LEFT SIDE OF THE BY THE FUSE BOX, THE WIRES RUN UP INTO HARNESS THERE.

IVE PULLED DASH APART ON PASSENGER SIDE ALL GROUNDS ARE GOOD, NO OPEN WIRES, PULLED HEAD UNIT OUT CHECKED ALL GROUNDS THERE, WIRING IS FINE. PULLED BACK SEAT OUT SIDE PANELS OFF TO SEE IF WIRING WAS FINE AROUND DOOR SENSOR,

 

So, aftermarket radio then?

Pull it out, verify correct wiring and go from there, it's obviously a wiring issue.

 

HAVE PULLED HEAD UNIT OUT ALL WIRING IS GOOD AND SOUND. I HAVE DONE PLENTY OF HEAD UNITS IN CAR OVER THE YEARS, NO ISSUES WITH THE WIRING ON THE RADIO.
