Dakota - electric trim on co-pilot side?

[DesertNomad]

I have a 79 Dakota with electric trim on the left side of the pilot yoke. The physical wheel is pretty stiff to turn - certainly more so than the 172 I trained in. My wife is learning to fly a bit with a pinch-hitter course from our CFI. What would be involved in putting an electric trim switch on the co-pilot yoke?

Thanks.
