V6Jim Posted July 13, 2007 Share Posted July 13, 2007 Hi, Folks. I'm fitting a new Towbar to my Bessacarr E765 (56 reg) in the next few days. The bolting on bit is easy, but have any of you got any advice on the best way to do the wiring. I'm kind of assuming that all I have to do is just splice the 7 cables into the appropriate cables at the back of the van. Please let me know if any of you have any hints or tips for a tidy job! Ta very much, Jimmy Link to comment Share on other sites More sharing options...
colin Posted July 13, 2007 Share Posted July 13, 2007 Check with manufacturer, it may be the conectors are already there and then all you have to do is plug in. Link to comment Share on other sites More sharing options...
V6Jim Posted July 14, 2007 Author Share Posted July 14, 2007 That means having to contact the Swift Group for help....not something to be taken lightly! I may try.... Thanks, Jimmy Link to comment Share on other sites More sharing options...
davenewellhome Posted July 14, 2007 Share Posted July 14, 2007 The only suggestions I'd make is firstly to contact the towbar suppiler as they may have a specific wiring kit. The other suggestion is to solder your connections and insulate them carefully, do not use bodgelocks. D. Link to comment Share on other sites More sharing options...
Mel E Posted July 16, 2007 Share Posted July 16, 2007 And another tip is to be careful what you bolt the towbar onto. Many motorhomes with long overhangs have rear floor supports bolted to the main chassis to support the rear floor. I think these are not suitable for fixing a towbar to, but it muct be fixed to a main chassis member. Dave will correct me if I'm wrong!!

g4oip Posted July 16, 2007 Share Posted July 16, 2007 I use H/D 7-core and connect all these to live [but later] then a separate fuse box, solid copper earth strip for all the earth connections separate relays for all connections to trailer. then pick up sensors from rear wires [soldered conns only-insulated]take these in light duty 7-core to relays at front and take supplys to lights etc via. more H/D 7-core and you will not lose voltage at the trailer or whatever. Make a suitable box for relays[Tupperware] and secure then connect to batt. for testing.Sounds complicated but its not and dont forget to take earth straight from the batt. to rear to avoid earth probs. later.

Clive Posted July 16, 2007 Share Posted July 16, 2007 Hello Alec, Like your shack, and is that a space suit (less helmet) you are wearing? I have used your relay method before on vehicles where the electrics are 24 volt and the tow bar requirements 12 volt - plus a 24 - 12 vold DC-DC converter. However its a bit OTT for a simple instalation. On some modern vehicles the lamp currents are all monitored by one of the vehicle computers. Toyota landcruiser for example being one. Fitting towbar electrics is simple and there is no seperate indicator for the trailer, but remove one bulb and it knows! On more traditional systems with a seperate flasher unit there may be a spare terminal marked P2 (from memory) which can be connected to a seperate indicator lamp to indicate when the trailer indicators are working. Or Buy one of those little modules that connects between the trailer connector and the rear indicators of the vehicle. These monitor the bulb current and sound a beeper.

Mel E Posted July 16, 2007 Share Posted July 16, 2007 Just for info, it is a legal requirement to have a sounding bleeper to repeat the indicators when towing a trailer. Mel E ==== Link to comment Share on other sites More sharing options...
Clive Posted July 16, 2007 Share Posted July 16, 2007 Not sure you are right about this Mel. Its a requirement to have a warning that they are faulty when fitted but not that it has to be audible. Have a look at the STVZO regs. Link to comment Share on other sites More sharing options...
Mel E Posted July 17, 2007 Share Posted July 17, 2007 Clive, Can't guess what stvzo regs are, but this requirement is part of RVCAU (Road vehicles Construction and Use 1986, as amended) - the part that applies to trailers. Mel E ==== Link to comment Share on other sites More sharing options...
