Question about 2001 BMW 5 Series
Whilst I have been able to fit my tow bar on my 2001 E39 M-Tech Sports Tourer, I am unsure how to wire up the standard 12N socket. What wire colour does what? What side do I pick up the wiring loom? My car also has parking sensors.
Your help on this is appreciated.

use the wires inside the hatch behind the plastic panel on either side. Wiring for your car is as follows -
Parking Lights YELLOW (-) 1K OHM RESISTOR AT THE STEERING COLUM HARNESS USE A 1KOHM RESISTOR Brake Lights WHITE/TAN (+) AT SWITCH Reverse Lights VIOLET/BLACK (+) 72 PIN CONN POS 6 BEHIND PASS KICK
Good Luck, NGK

You need a Trailer Light Power Module - Uhaul, or anywhere that sells hitches and accessories. The module will power the lights directly from the battery - it still hooks into your car's lighting system, but only for sensing purposes, it doesn't put an extra load on the lighting system.
Here's an example from Uhaul:
Hope this helps :)

black socket, black 7 core wire
pin 1 yellow left indicator
pin 2 blue, rear fog light
pin 3 white earth
pin 4 green right indicator
pin 5 brown right side/tail light
pin 6 red brake lights
pin 7 black left side/tail light
Grey socket grey 7 core wiring
pin 1 yellow, reverse
pin 2 blue, supplementary feed (ignition)
pin 3 white, earth
pin 4 green live feed (battery +)
pin 5 brown not connected
pin 6 red supplementary feed (ignition)
Pin 7 black earth
On the discovery there is a purpose made plug behind the panel on the drivers side rear, behind the rear lamp
i think the relay you have bought is for lamp failure you just need a normal 4 pin 30 amp relay.
Good luck Davelee
