Shift Light /4, what works? Options

[Seabird]

Hello. Adding a shift light because they are cool, no really I am adding one cause I need the reminder sometimes. I ran through my normal search routine and I see some posts that say "they generally don't work on Porsche's" and say nothing at all.

I categorically reject both these answers.

I bought a ProformParts light from Jegs/Summit because sometimes I am cheap. After mounting it and wiring it I found that it does not work. The instruction were useless to help troubleshoot why. It basically says, "you probably wired it wrong; there is nothing possibly wrong with our plastic Chinese junk, check your power wires, what do you want for $50 you cheap female dog, have you checked your shoddy electrical work yet?!" ... that's pretty much verbatim.

In truth it was 11 pm and I did not bother debugging it. It will be first priority tonight.

I wired the red and black to positive and negative 12 volts and the green wire to the single wire at the back of the tach <from coil (-)>. The tach works as usual, which is to say spastic. (As part of my electrical upgrades I will be swapping the tach guts for the Sunpro guts.)

For Ignition I am running a Mallory Uni-Lite and a Blaster 2 MSD coil.

I will update the thread with a trouble shooting report tomorrow but for now lets hear hear how others have installed shift lights so there is something useful for future searches... Make, model, wiring, and success or FAILURE. Nothing wrong with reporting what has not worked.

Thanks,

Miguel
