Thread: RRS Trailer Connection - help needed

Hi all,

I'm about to pick-up a (new to me) 2010 RRS this week and I am trying to find some detail around the trailer connection setup.
My boat trailer requires the reverse light to be "active" so that when reversing (say down a boat ramp) it sends a signal to disengage the brakes on the trailer.

Can anyone tell me if the RRS is wired for this or do I need to get and auto electrician to make some modifications? I have to pick-up my boat from storage in a few weeks (250km away) and I won't have a chance to test it before I head up with the new tow rig..

Thanks in advance

Thanks for all your help with this..

It will have (unless already modified)

the black socket
Pin - Function - Wire colour.
1 - LH turn - Yellow
2 - +12V or rear Fog lamps - Blue
3 - Chassis Ground - white or Grey
4 - RH Turn - Green
5 - RH Tail lamps etc - Brown
6 - Stop lamps - Red
7 - LH Tail Lamps etc - Black

And the white socket
Pin - Function - Wire colour
1 - Reversing lamps - Yellow
2 - spare - Blue
3 - Chassis Ground (not pin 6) - white or Grey
4 - + 12V constant - Green
5 - spare - Brown
6 - + 12V Ign - Red
7 - Ground for pin 6 - Black

* So it should be OK to take the yellow from the white socket and put it into pin #2 on the black socket.
* The brake controller blue output need to go to pin #5 on the black socket. Many people have come undone here, interesting issues like trailer brakes locking when the auto headlights come on because RH tail is in pin 5.
* The RH tail lamp brown wire needs to be disconnected from pin 5 and joined to the LH tail lamps black wire to prevent errors about tail lamps not working.

I did all my modifications to the loom at the trailer ECU, so they are all out of the weather...
