Vehicle to Vehicle Tail Light Converter Demonstration - etrailer.com
see video.
he calls it 3 wire , dont let that fool you .
he doesnt count ground or Tails (parking)
your car:
nums are not pin nums, only items.
1- white , ground (wires to trailer directly) to 4 above.
2-brown, Tail, again, wires directly to the 3 above.
3-yell/black , left blinker ( non integrated car)
4-gree/wht , right blinker (same)
5 Blue , stop (note stop on suzuki is a seperate signal)
3,4,5 must be wired thru an adaptor convertering 3 wire (car) to 2 wire trailer.
the trailer has integrated stops and blinks. ( my bet, and is common)
a battery placed on on the trailer can test this out.
place neg, battery term to trailer ground (look to discover this)
the walk the battery + term on each of the other pins not ground.
you will see which color wires does, what. easily.
safety:
use an 20amp inline fuse to test this or the wires can burn if you hit ground accidentally.
this adaptor is very common.
the adaptors that have 12vdc as input , are superiour as this design off loads
all current from the stop/tail. brake circuits.
i will find a source later.
cheers.
