Ok so im Going to use Holley's HP Efi set up with my new TPI 383 but along with the old ecm harness went the wiring for the vapor canister so how do i wire is to work by it self as the egr valve is being blocked off as well were do i connect the vacuum line now.
#2 there is no provision for the speedo as it works through the vats so how can i make it work with the new set up.
#3 how do i wire the converter lock up there are several parameters to control it what would be the simplest way to wire it and control it to make it work right?

It won't , ( unless the Holley has a CCP control function )
will need to vent the tank directly like old skool cars

Speedo has nothing to do with VATS

Probably going to need one of these to supply the speedo signal that used to come from the ECM

Awesome thanks for the answers with the canister tho how do I go about this this is the first car I've ever dove this deep into so when you say vent it directly I'm still lost on how to make the purge valve work I can't just run the line from the tank to it and that's it right
