Hi,
I use a 7 pin flat plug for towing. Yesterday whilst towing caravan the light on brake controller went out & I cant find the fault. Have cleaned & checked connections. Can anyone tell me which pin is used for electrical brakes.
Thanks
Willy

If all else fails, it's usually the blue wire

I once experienced intermittent light flashing from the controller while driving. I discovered there was an excessive amount of strain on the plug wiring after I had moved the bracket. After repositioning the wiring and giving it more slack I haven't had a problem since.

Also my advise is to ditch the 7 pin flat and refit a large round (either metal or plastic). When I had a 7 pin flat I always had problems with the connection being 100% from no indicators to loss of volts/power to the van. After fitting the round plug all has been good. Also fitted an Anderson Plug for power direct from the 2nd battery to the van with excellent results including reduction of voltage drop to the fridge while travelling.
