Rusty garbage hoarder.
Possibly dumb question. My J20 is magnum swapped, and I want to add the magnum cruise control back into it via the mid 80's FSJ/GM column multifunction switch.
I know the multifunction switch is 12v, but is the magnum computer a 5v reference, or 12v for the cruise. I have pin out and wiring diagrams for both, I just want to make sure I'm not gonna fry my ECM.
It would be nice to have on longer road trips.
Edit: I should mention the ECM is a ram computer running a ZJ powertrain. same=same.
