My 22R has kicked the bucket after 386,000 miles and I happen to have a 22RE that is in good shape, but none of the wiring or the ECU. Since my truck is my daily driver and I need to get it on the road ASAP, I was trying to find the best way to do that with what I have available.

Thats reasonable. I cant stand the guys that want to carb there efi trucks because ''its easier''. Go ahead and bolt up the intake, carb, ect. from your 22r onto the re and your good to go. but id suggest holding on to the efi parts and keeping an eye out for the rest of the  parts you need to do the swap. do the research and when the time  is right go efi.
