ok is it possible to run an aftermarket comp (dfi) and retain the stock gauges? oh and this is a lt1 car, not sure if that matters!

 

The volt,oil pressure and Temp will run without the stock PCM. The speedo and tach will not.

Just wire them and then you will have to ground the wire on the cluster. Depends on what year it is but all the wiring for the 3 plugs on the pass side kick panel are on shbox site

 

its a 94, so it is possible as long as i leave the stock pcm in?

 

Is what possible?

Thos 3 I listed will work without the PCM......tach speedo etc. you will need the PCM

 

ok by leaving my stock pcm in, i can piggy back the dfi and all my gauges will work!
