i finally have a tach. i got tired of fighting the system in the car so i just used an aftermarket piece. msd #8913. Took me about 20 min to get it in and set it up. 70 bucks is alot more than $1.19 for the resistor but for the time and aggravation it will now save me its worth it. Still have no idea why the resistor didnt work for me but atleast there is a second and solid option for the next guy to do it.

There are wiring schematics readily available for download that show wire colors. Look around and you'll find them..."Useful saved posts" is a good place to start. And at least in my NA, there is no factory speed sensor, so no signal at all there unless I run an aftermarket sensor.
Put some info about your car in your signature so we'll know what you are working with. And do a little searching
