Ok, so I bought a Sunpro tach from AutoZone. Its got a 4 wire hook-up, power, ground, illumination, and RPM signal. Got everything wired up, it get power, but no RPM needle swinging activities. I wired it to the Blue RPM signal on the dizzy, but it didnt work...any suggestions? The tach could be ---- to...It did come from AutoZone.

STD, no tach. thats why I had to buy this rice *** HomoZone tach.

thats what i'm saying jago....just cus the car doesn't have a tach doesn't mean they take out the wire that sends the signal from the ecu to the cluster connector

you have power or illumintion ? you prolly picked a bad power source hook it up to something thats always running when the car is on or something

I have both, just dont have RPM pickup.

cool, I assumed that the STD chassis harness didnt have a RPM signal wire. Thanks. That wire will still be blue? Im going schematic hunting after I post this.
