Has anyone had any success installing an original 1963 tachometer with a modern EFI computer motor?
I've had the tach restored and re calibrate for a V-8 and I have to have it in my car. Problem I have a tach signal wire from my coil but the tach doesn't wire up that way, so I need to figure out how to make it work.
Anyone.......
Tach has three wire: green, red, black. Signal wire from the coil is green. Common sense says, green to green, black to ground and red to power. NOT. I've read somewhere about a filter to correct the signal but now I can't find the info. HELP.
