I'm looking at buying a universal automatic transmission computer ( http://www.powertraincontrolsolutions.c ... ontrol.php ) for my 1UZFE powered 1993 Toyota Surf. Just wondering whether anyone had access to a decent wiring diagram for this transmission?

Personally those ones are over priced..
Here is a unit which is specifically tailored to our auto's the A340 variants
You can do everything the one you state can do...
Also has wiring instructions for the Toyota auto...

But basically its three wires. and sometimes 4 if uses a solenoid for line pressure.

Search the forum....I did an bit on manualising the auto and it has a bit on the wiring...

It will be in this lot somewhere

Is there any differences in the shifting/wiring between the A343E and the A340E? I finally have a PCS TCM2000 on the way. Also is there anyone else out there that has used one of these on the same transmission?

No they both shift the same way.....
However some have 3 solenoids and some have 4....

The forth one replaces the cable operated line pressure valve with a solenoid..

I don't know of any people who have used that unit in NZ...
Most have just manualized it.
When you do it, you will need a TPS if it doesn't already have one and also tap into the speed sensor.
Post up what you do....

Manualized is way more fun!
