Ok im finished
I put it on the back of the clear LCD glass AND the front, i tried it a few different ways trying to lighten it up but it was dark as well without the headlight/backlighting on. So I modified the wiring just a tad so that the displays backlight is on whenever the ign is on instead of just when the lights were on.
On the drawing of the wiring
CUT THE Br (brown)
ATTACH the Br on the display side to the Bl/Br (black w/brown)
Cover and seal the Br coming from connector as this will have 12v on it when the headlights are on.
