Sure, wiring is a bit of a pain to photograph as to not remove my drawer system I'm only working through the small access panel on the rear right.Brilliant - have you the time to show us the wiring and the individual modules in situ?
Either way, let's try to walk through it.
The modules are SoundOff Signal mPower 3" lights, there are a few different versions, but these are the "quick mount" version which just means that it comes with 3M VHB applied to the back of the light for mounting (instead of being bolted into place). They are available in a array of colors and types. I went with the dual color, but single color and tri-color are also available.
Wiring the lights is straight forward. They come with a 5 wire pigtail: Red, Red/White, White, Green, and Black.
- Red = Color 1
- Red/White = Color 2
- White = Color 3 (or a modifier for dual color use)
- Green = Flash pattern/synchronization
- Black = negative/earth/ground
- Red/White is for the white illumination, and goes to the output from my Switch Pros controller for "rear scene"
- Black+Green is grounded at a point near the factory towing control module in the rear cargo area
- Red connects to Output 1 on the added flasher and is where it gets ever so slightly more complicated
I have a Feniex 4X flasher (also called the H2220) installed in the cubby next to the TRM (factory towing module). This flasher uses 12v positive, negative/ground/earth, up to 3 separate "mode" triggers, and up to 4 light outputs. It is wired as follows:
- 12v positive = 10A fuse in my BlueSea fuse block (powered from my aux battery)
- 12v negative = ground point adjacent to the unit
- Mode 1 = Blue/Orange wire from TRM (as referenced here)
- Mode 2 = to a blunt cut/capped wire left under the back seat for future use
- Output 1 = Red wire going to lights
