I could have a rpm switch hooked in to the solenoid switch and have the solenoid plug. I could hook the rpm switch to a injector also. All you would need to do is run the power/negative for the rpm switch run. If you want the solenoid, rpm switch hooked up before I send out, injectors and pcv cap I could probably do it for around 450$-500$ depending on what rpm switch you want.
If it's still available after new years we'll have to get into details a little bit more. I'd like to do this but it's a bad time of year I'm sure you understand, that and I'm not going to BS you and tell you "next paycheck".
