T3bunny, thanks for your help.
I am using MSII.

Kdog on Lextreme has helped me out alot as well. The following quotes are all Kdog.

I found a wiring diagram for the O2
1.RED ---HT1
2.BLK RED----B
3.BLK - 02 +
4.BRN - O2 - ground

Blk/Red goes to a switched +12V, its power for the heater, the Ht1 line switches to ground through the ECU to turn it on.

TPS
1- brn ---ground
2- grn ----switched
3- yel -- position out
4- blu-red- +5V

"Its a normal 3 wire TPS ie +5V power, Ground and position out. The 4the wire is an idle switch to ground.
Brown - Ground
Blue/Red - +5V
Signal is one of the other 2, not sure from the top of my head.

For idle speed control leave the Blk/Red wires disconnected.
The others can go to l1,lb 2a,2b,
Blue/Wht??? 1A
Yel/Red 1B
GrN/Yel 2A
Grn 2B
If this doesn't work switch the polarity of them around ie wires 1A and 1B or 2A and 2B until you get it to move correctly.
