Dash mount shift light option?

[Terry Kennedy]

FYI the previous research I did on the pin outs was incorrect, there is 1 12 volt wire, the other 3 are grounds (not positive) On my 3 color LED's they share a common Hot wire, and then each color is individually grounded which exactly matches how the dash is set up to operate.

I was going to say "You could have saved yourself some time by looking at the manual in the Documentation Library", but I just checked and neither of the two versions of the dash manual posted there had the shift light pinout. So I uploaded a third version of the manual that does have the info:

Attachment 285

By the way, this "switching the ground" is extremely common - far more than "switching the power". As an example, the Check Engine LED works this way, too. This is called an "open collector" driver.

I also didn't realize until today that the stage 1 2 and 3, are not "on" one at a time, as the rev's climb it's stage 1 on, then stage 1 AND 2 on then stage 1 2 AND 3 on.

so for my LED's it was not lighting up Green Blue Red it was lighting up Green, Aqua, white

On top of that I had them wired differently than I planned so it was Blue Aqua White as seen in this video, and my android phone takes horrible color so it doesn't represent well.



so I decided what would be better, is if I run the wiring Green stage 1, Green plus Red stage 2 (which makes Yellow) RGB stage 3 stays white...Looks good to me.



I'll probably mount 4 under the bubble, and 2 up where bolus mounted his,
