Got rid of PCM have questions Okay guys i am in the process of finishing up my SBC conversion into my 95 camaro. Now i have some questions about the electrical.
I pulled the entire pcm along with the wiring harness when i pulled the motor because im going with a stand along efi system. But i need to know how i can run the speedometer because it originally ran through the pcm correct?
is there an aftermarket VSS i need to be able to use the factory speedo?
Also is there any other electrical issues i might need to resolve?
Thanks guys

The stand alone harness I got from PSI has a VSS in it. I don't know if all harness makers put that into their harnesses, but, I'm guessing they do if you're using a GM PCM. You don't say what you are going to use for the ignition? Being your project is an F-body, what aftermarket EFI? There's no room under the cowling to run a distributor or a top mounted TB without chopping the cowling and firewall to shreds.

I'M running the new FAST EZ EFI 2.0 which has everything built in except the vss.
Also i am using the MSD flattop distributor which should clear without issue. and have a custom intake manifold which should clear even with the throttle body on top.
Anyone got some ideas on how to get the speedometer to work?
can i use an aftermarket speedo like an autometer or something?

Okay guys im bringing this back up from the dead.
It looks like i'm going to have to put a LT1 ecm back in the car to run the speedo and the air conditioner. But i don't have any of the wiring harness so i need to know if/how I can wire this up. I only need to run those two things
