You are quite right, pin6 on 12n is for brake lights & pin6 on 12s is for running fridge, ie power off with engine off, confused? you will be. 2 choices here methinks, pay somebody to do the wiring for you or diy & pay somebody far more to sort out the resulting damage.
How old is your car? If made within the last few yrs it would be easier to get a dedicated loom. Are you wiring just for a trailer 12n, or for a caravan 12n/12s or 13pin?
Cars made this century generally have canbus systems, all cars made within the last few yrs do. You cannot scotchlok wiring to to lights in the boot as in yrs past.
The cheap way is to use a bypass relay, the better way is to use a prewired dedicated loom either for 7pin trailer or extra loom for 12n/12s caravan with twin cables. Many prewired looms come with the new 13pin push & twist socket as this is taking over from the old system.
Hi Tentz - firstly thanks for replying - the car is 03 - Ford Focus - we are just wiring a single plug, dont and have never had the need of a double plug, - ohh eck cant you tell were used to doing it the old way
