Honda wiper relays(from CRV to wgn???)?

Has anyone tried to swap rear wiper relays with other Honda models? My wifes CRV rear wiper does 4-5 fast passes then automatically switches to intermittent. Wondering if I could pull one out of a CRV and use it in my wagon? Anyone have some insight???

I'll dig up a pic. It was stock, just a dial where that funny little recess normally is on other wagons.
