91 tachometer problems
I have a 91 miata with a 99NB guage cluster everything seems to be working EXCEPT my Rpm's They dont work at all. The only reason I can think for this is because 91's get there tach reading from the ignitor where as newer models get their readings from some sort of module....Any suggestions?
This is how I have it wired right now:
91 (from Dash) - 99 (from cluster)
Ignitor (Yellow/Blue) - Green/Orange
Ignitor Switch (Black/Blue) - Violet

ok tell me what yall think this is what Ive came to the conclusion after searching and searching...
This is a chart I found of colors.
Wire colors. The tach signal is the same color at the ECU.
Ground Power Tach signal
1990-93 Black (2D) Black/yellow stripe (2K) Yellow/blue stripe (1H)signal
1994-97 Black (2D) Black/yellow stripe (2K) Black/white stripe (1H)signal
1999-05 Black (3J) Black/yellow stripe (1C) Green/orange stripe (2K)signal
You would think yellow/blue goes with green/orange well that didnt work, and I dont have a black/white..
So I found the attached picture of the ignition ...
So If I ran a wire from the black/white, and connected the three colors (yellow/blue, green/orange, and black/white) together into one that it would work?
