I got a curious question on the injectors.

Ok my VATS system is being lame and I was curious if I could hook up my injectors up to a toggle switch of some sort. I plan on doing the same with the pump and everything if this is possible will someone tell me which wire to cut and hook it up to. Thank you.

not a good idea, the injectors are fired thru a DRP initiated driver. the easy way to fix the problem is to disable VATS. That's as simple as getting a new prom and plugging it in. No wiring to change, no circuits to cut, no electronics to figure out.

How much would the PROM cost since I got the lame TBI set up which I plan on taking off in a few years to go to a supercharged carb set up. I am looking for a temp fix that will last a few years. And its not easy for me laying under the dash to do wiring to bypass the VATS system. Thank You.
