I'm going to install a Trailer module (TRM) into a Volvo V70 2005. There are are two sockets on it (a gray and a green one). I found the cable from the Rear electrical module (REM) which should be connected to the gray socket on the TRM. But I also found two cables with similar green connectors. I think the one with 5 wires should go into the green socket of the TRM, but where should the other go? Connectors for TRM

  • Where is the other green connector? Show all three and then we may be able to work it out... – Solar Mike Feb 23 '19 at 7:13
  • @SolarMike I can't find any third connector in the reach of the two cables in the picture. And both of them individually fits in the green socket on the TRM. – janlindso Feb 23 '19 at 10:59
  • Since all these items apparently need a software download from a Volvo dealer, that's would be the obvious place to find out which cables go where. Alternatively, you need a circuit diagram. The green connectors obviously have different purposes since they connect different numbers of wires. – alephzero Feb 23 '19 at 12:25
  • @SolarMike I think the OP means the green socket on the panel of the trailer module in the picture. It's impossible to see what it's connected to unless you can take the trailer module case off somehow. – alephzero Feb 23 '19 at 12:29
  • I can see two green plugs but don't see a socket anywhere - which I hoped to see just in case there was some clue with the number of pins... – Solar Mike Feb 23 '19 at 12:32
