I Want to install a Tach....help with wiring

Hey,

I have a 1993 Geo Prizm LSi and the smart engineers didn't put in a tachometer on my manual car...

SO I'm installing one myself. I don't know where to connect the green wire other than the "test connector" but I don' know where that is. The instructions say connect it to the negitive on the ignition coil.

on the distributor there are two connectors. One has two black wires, one with an oragne stripe. the other connector has 6 wires; red, black, green, blue, white, and white with a black stripe.

Any help would be great.

Thanks,
Larry
