Sorry to barge in on this topic, but I have a strange problem.
Just fitted me a towbar and connected the electrics. I went the easy way and cut off the socket and soldered the wires. Heatshrinked of course. Now the strange part. I fitted the 4 pin relay and while the speedo was out I thought I'd fill all the empty bulb sockets. The missing ones were: towbar, seatbelt warning and catalyser heat warning (I guess that's what it is) Now when I connect the trailer and use trun signal, TWO lights blink with the turn indicator. Addition to towbar light, the catalyser light also blinks. I guess there's a reason why there's no bulb from the factory ... Anyone else have any experience with this?
Another matter, not related: I don't have rear fog's. Switch works, indicator lights up in the dash, but no juice to bulbs. Weird thing is, there IS juice in caravan connector wires... Is there a missing relay, fuse or something? Checked all to my knowledge, everything is in its place and no blown fuses ... Not that I need the fogs every day but MOT certainly checks them ...
Any help appreciated.
