i havent done this swap, but i dont see why you couldnt, I hooked up a keyless entry system on a dodge, and we tapped off the battery, the ignition, threw in a couple relays tapped off the power door locks, made sure it was all grounded and boom! she worked!
I believe there was also a Module the remote activated to get it all goin.
If you do it...........a writeup with pictures would be greatly appreciated.
