Harlan light not working right I installed this shiftlight about a year ago and it does not come on in 1st. and 2nd. gear. It comes on in 3rd. gear everytime. I don't know what the problem is. I have the light set at 6,400 and the rev limiter is 6,800 so I know I should see the light come on before I hit the rev limiter. ALso the light always comes on when you turn on the car like it should so I don't know whata the problem is. I just think it's hurting my times because we all now how acurrate the stock tachs are. 
how are you guys making the tach signal connection??
The tach signal never changes format, and the light doesn't know the difference in gear.
Please tell me you're NOT using those crimp on splice tap things.

ummm, no comment 
I'll solder them, hopefully that will fix everything. I thought it was really wierd that it seemed to ONLY do it in 3rd. never did it not work in 1st or 2nd.

I just don't trust non-OEM style crimp terminals or splices, and i still solder them anyway
Most electrical failures are due to mechanical failure first, see it way too many times
