Converting my 1989 CSX to a true T-2 car, as I purchased it with the VNT already gone. I would like to run the current SBEC that i have chipped in it, but I'd also like to be able to get rid of all of the VNT specific solenoids and connectors for that car, and just electronically and mechanically, make it the same as a SBEC Turbo Shadow. Paypal is ready, I'm located in CT. Thank you!
I'm almost certain that you can just disconnect the VNT solenoids and repin anything you need to at the SBEC connector. There wasn't that great of a difference between the two harnesses at all.
yeah just get the wiring diagram for the 91 sbec turbo shadow and you can check to see if the VNT specific solenoid wiring correspond to the factory T2 solenoids. I have a hunch that they used the same wiring for some of it. its not like the SBEC has limitless outputs to use. They would have to reuse some stuff.

FWIW - I’ve been running a regular turbo in a VNT car for ~20 years. No need to change the harness. Mine is a 2.5, so I was able to drop in a T1 SBEC. I could see how running a 2.2 would be more complicated, but I think your solution is in the SBEC, not the harness. From what I recall, one of the solenoids that controlled the vanes controls the wastegate on the T1. The other solenoid is not used. I can scan the wiring diagram if it would help. Not sure how much different the SMEC is - my experience is limited to SBEC.
The 89 CSX uses a SBECQuote:
