91 TF999 swap to 2000 32RH ?s

OK, so I just need a little clarity before I waste too much time. I have a 91 YJ with a TF999 that the converter, pump and seals are going bad etc.....
I plan on rebuilding mine with a few upgrades, but I want to swap in a used good condition tranny for the time while I build mine. I can get a 2000 TJ 32RH for very cheap and just want to clarify what it will need.

The newer tranny has a lock up converter, and i stat the only real differences? My TF999 has the CPS mounted on the bell housing on the driver side top and the standard neutral safety/reverse switch. Do I just need to wire a switch for the lock up converter and everything else stays the same? I am assuming the input shaft for the lock up converter is different than my non lock up so it will have to stay as a lock up. What are the down sides of wiring the lock up to a toggle switch? Can I mainly just use that as overdrive type of situation at sustained high speeds on the highway and leave it unlocked around town with no major wear on the tranny?

I am just looking for a quick swap since time is at a premium these days and pan on building my tranny when time permits....so thanks for the help.

I am looking for a good write up on wiring up the converter is you know of any.

FYI, it's all feeding to a built dana 300, so I know I am needing to get the speed sensor to hook my cable for the speedo to start working too......

switching to electronically controlled transmissions often presents issues (as well as, I understand, the lockup was the biggest potential problem spot in those transmissions.)

I'd look at Stu Olsen's site (http://www.stu-offroad.com/index.asp). He discusses several different auto swaps, and you may get some helpful info even if it's not exactly one he has covered.

Yeah, I've read over STu's info...and as I understand, the 32RH an the TF999 are both hydraulically controlled with the only difference being the 32rh had the lock up converter that is controlled by a relay in the valve body. I am curious if the lock up converter is not wired if it will act as an older tf999 with no lock up???
