TPS and RPM signal from the PCM is all you need! ... let me know if you need the wiring info, or just do a search.

Edit: I'm bored at home...

TPS signal is ... DK BLU wire at 24 on C2 (red)
RPM signal is ... WHT wire at 10 on C2 (red)

Only 1 wire goes into that point, just tap into that

edit: I don't think I was that clear...

Take the the plastic covers off on the outside of the PCM connectors (be careful, they break easy; use a tiny flat screwdriver to get the tabs off the connector face). You'll see little numbers next to each wire, look for the number you want and verify the color of that wire before splicing in. I forget which is C1 (blue) and C2 (red) location wise 'cos the color is only on the inside, so you can simply unhook it to see which one it is by using the bolt in the middle of the connector.
