Your Taurus 3.0 was origionally equipped with a 3G, which is actually a better platform than the 4G. Also, the explorer housing is completely different, and it would be a waste of time to swap the housing to put a 4G in place of the 3G.
I have a last year's model 200 amp unit on closeout that would be a direct fit your taurus for $249 shipped. Let me know if you want it, I only have a couple left. Contact me at: [email protected]
