Car Forum / Volvo Cars / June 2004Tailgate wiring 89 245
Before I order new tailagte harnesses, can someone tell me if mine have been tampered with? The passenger side looks original, with a single 3-wire connecter covered in foam. The passenger side though has 3 single wire connectors and some electrical tape. I am afraid that ordering a harness would be silly because I'll just have to cut and splice the damn thing anyway. Does anyone know if what I described sounds like the factory connections? Also, buying new hinges to repair a severed ground wire seems excessive to me. Any clever workarounds out there? Thanks Danny Hi Danny, Are you describing what is visible, from above, in the hinge itself, without any dismantling? Andy I.

I've had the tailgate harness replaced twice. It seems to last about five years. I now park with the rear of the wagon in the shade...... when I can. Good luck. Andy I.

The harness protrudes about 6" inside the roof of the car where it connects to the main harness, there's a connector there, so it's not like you have to rewire the whole car. You can use the unflexed parts of your old harness (down in the tailgate the wires will still be in good shape) to bridge the gap in the broken ground wires. The ground wires are a little thicker, so you can use 2 pieces in parallel. Just make sure you solder the connections. Note that the ground wires were not even in the hinges in the early cars, grounding was done through the structure of the hinges and latch.  SignatureMike F. Thornhill (near Toronto), Ont.

Check the hinge pins very closly and make sure the holes are not out-of-round. The pins will wear the holes oval shaped which can cause the door to rattle and sit crooked. -- -don '81 242t '89 744ti Mike your advice seems great but I don't clearly understand it. Are you saying to use the old harnesses and just pull some wire throug and reconnect or buy new harnesses and use the wire from the old ones to make up any distance that doesn't meet up? And on the ground wires, you say use 2 pieces in parralel, could you explain this like you would to a child, because I'm not really getting the picture.

Tape the ends of new and old harness together, and use the old one to pull the new one through. There isn't much space in the tailgate, so don't make a huge blob of tape at the connection. Make sure you've made note of where each wire goes before disconnecting them. Take pieces of the old harness where they haven't been flexing in the hinge. Cut back the ground wires about 1" from where they've broken. Solder 2 pieces of the old harness wires across this gap. SignatureMike F. Thornhill (near Toronto), Ont. NOTE: new address!!

Also Mike, in your mention of the older designs using the tailgate hatch as ground connection, can I just rely on that? I'd be perfectly happy to have my tailgate wipers work only when the hatch is closed if that is the scenario.

My '74 never had them, and everything always worked in the tailgate, whether it was open or closed. On the newer cars there is more rubber in the latch area, but there is still metal to metal connections in the hinge area. Obviously it was causing some problems in some cars or the wire wouldn't have been added. SignatureMike F. Thornhill (near Toronto), Ont. NOTE: new address!!
