Tachometer info
 

I no longer have my CAS hooked up. My fans are on a switch and car is run by the tech.

Does anyone have a diagram of what wire from the tach i need to use for the tach output on the tech? The tech I can find easily enough, but i cant seem to find the one for the stock mazda dash tach..

I dont want to have to put a seperate tack if I can help it. I'm not into that..

Thanks
