I’m about to use my P38 for towing a caravan and am considering changing the towing electrics.
My P38 currently has the black 7N towing socket on the back bumper. It’s a genuine LR socket on it, from reading online it’s likely connected behind the tail light cluster on the OS of the car.
I’m thinking of adding the white 7S socket so I can run all of the caravan electrics properly. From reading on the net, I gather there’s a socket for that to connect to behind the tail light cluster on the NS of the car. There appears to be 2 part numbers when looking online...
AMR3007 - Towing Harness
PRC9233 - 12S Towing Socket
From what I can gather, AMR3007 plugs into the plug behind the light cluster and PRC9233 connects to this to give you the additional socket. I’ve read there’s also an additional relay that you need to add to stop it flattening the car battery.
I’m thinking of combining both the 12N and 12S sockets into a 13pin electrical socket on the back of the car as well.
Does anyone have any experience of the 12S socket on the P38?
