Autometer Tach Install questions

[pankopp]

Hello everyone,

I am in the middle of the install of an autometer tach in my '93 ej-22 powered Porsche 914...

I have the tach and the required adapted hooked up except for the ecu signal that must be taped into the coil harness.

I know the three wires are; blue, red-green, and yellow-red... but am unsure which wire to tap.

Any help would be awesome.

Thanks,

pankopp

Sorry, I don't have an answer for you about the tach, but I am interested in how the swap is going into a 914? That's a cool idea! Did you have have to do a boat load of fab work or was it easy? I would love to see some pics of your project.
