Wiring an aftermarket tach

[sean_carole]

Hi guys, i'm trying to install an aftermarket autometer tach on my 1992 alegro bay motorhome on an e-350 chassis with the 460 motor. Any idea which wire i attach the green wire from the tach to on the distributor? Any info would be greatly appreciated!
Thanks.

You attach it to the coil and not the distributor.
You attach it to the tan wire with a yellow stripe. That is also the non-power side of the coil (- side).

The power side is a red wire with a light green stripe, you do not want to attach to it. Unless you are also after power to power the tachometer also.

Okay thanks subford, i'll find the coil wires and try to locate the correct wire and attach tomorrow.
