Alright I'm installing MS on a 6bolt, and I'm wondering has anyone done this and can give a lil information on installation... TPS shows 3 wires on diagram, but mines has 4... PM me!!!

3 wires are
1. power (usually a 5v reference)
2. signal
3. ground

the 4th wire on the 2g tps is for the throttle stop switch i believe but dont quote me on it
this is just off the top of my head

1gs have 3 wire tps. 2gs have 4 wire with an integrated idle switch.

it has been done before, i don't have the links saved anywhere but a quick search on the subject should yield the results you desire. i know that there is a link on DIYAutoTune.com Megasquirt Kits / Assembled Engine Management Systems, Wideband o2 Sensor Systems and tuning products on how to MS your 4g63 car. and yes the 2G TPS three wires are for the TPS and the 4th is for the idle position switch.
