the secret here is to buy a trailer harness for the vehicle ( available from most tow bar supply and fitting shops )
it is a set that just plugs into the existing harness at the rear light assembly ( piggy back arrangement)
from there you wire the male and female plugs as per the color code that is on the paper that comes with the units
saves cutting into the car harness and causing real electrical problems
please dont ask me iam colour blind ,but to overcome this i use a multimeter or a little light and test for current this way ,going by the so called wiring colours is a disaster for me not only the colour thing but the wireing can change colours owing to different suppliers of looms in manufacture ,they run out of one colour and use another ?? you name it i think i have seen it
Hello, if you have a test light handy with a sharp tip on one side than, start with your parking lights on and check to see which wire it is, if you have a heavy bag of potatoes or similar, you can use this when it comes to the brake lights :)
Your best bet is to go to an auto parts store or dealer and see if they have an adapter for trailer lights. Most of the newer vehicles have adapters the just plug into the existing wiring harness and you don't need to worry about splicing things. Also on some vehicles hooking up directly to the wiring harness doesn't work too well because of the circuit not being able to support the extra voltage drop. The adapter usually have that taken care of.
Well you have what is called a BUGGER.5 dont go into 4 so the problem is either the trailer is OLD and never had stop lights OR the white wire is your stop lights and it earths through the towball (but it shouldent ) so either someone has cut out the stop light wire .so check rear lights What colour is stoplight wire. As all DC wiring for trailers are 5or 7 core wires 5 for trailers and 7 for caravans..
