4Xtruck

A drunk driver spun out on the freeway and came to rest right in front of me. I had no place to go but into him. My truck is being totaled by the insurance, and 310,000 miles on a '94 won't give me enough to buy a new truck, so I went to the junk yard and got a front end from a '93 V6 4Runner. I cut off the 4Runner cross member/frame behind the battery stand and the same on the other side. It looks like everything will bolt together fine, but I do have some questions.

1) Can I attach a 22RE radiator to this 4Runner front, or do I need to pay more for the larger 4Runner radiator?
2) There is an additional electric fan in front of the A/C condenser, whereas there wasn't one on the original truck. How do you recommend I connect this to power (A/C circuit? Ignition circuit? Direct circuit? Other?)?

I need to wait till Wednesday to dismantle this truck, as the insurance appraiser will be out then. Will there be any other challenges anyone is aware of in making this change?

EDIT: The 22RE radiator fits perfectly, so that part is resolved. How about hooking up the fan?
