Well, I finally broke down and ordered some Autometer Sport Comp gauges. I got the trans and engine temp, oil pressure, fuel in the 2 1/16" size and the 3 3/8" 160 electric speedometer and 8K tach.

I'll fab me up an aluminum face plate to replace the stock cluster.

I'll figure it out eventually haha, but does anyone know if i can just plug the vss signal into the speedometer input on the gauge? it says it's for like 200 to 40,000 ppm. I guess I can.
Then I guess the white wire is the one to use for the tach.

thanks,

allen
