But mine also has can bus so I have no choice but to swap harnesses

your right.I agree!!
here is the thing Im having trouble with.

the transmission has a harness that also connects to the electric shift transf. Im not using that im using my manual.(ill have to change inputs) and rewire to hook up to my case anyways.
and that harness goes to Two plugs, connects from there to TWO plugs and also goes to the engine ecm.
thats all fine, but the TWO plugs that it ends at is supposed to hook to the cab harneess (the one from the driver side firewall, that has the fusebox and headlights all on one harness.)
the problem I have is thoe two plugs wont hook to MY harness.(cab/firewall)
Is all I have to do is Change that harness ? and will it still work with my NON sentry system. I would think it would but thats where Im Confused...HELP

your helping me so I thank you ever so much.

Ill have to look into a Smarty i guess. will the JR do?
