It's mounted on the top of the bellhousing, under the throttle body. See this post from stevepaa:

It's the one on the right in his pic. Note the wire colours differ from '97 diagram

Thank you .. I see its behind some large connector. Have to remove the connector to get to the clip. Would you know if the wire is cliped to the tranmission?

I'm not sure, sorry.
There is a plastic ducting running across under the scuttle which the loom appears to enter.

I'd take the TB off as it's only 4 bolts and a gasket. Should save you some grazed knuckles.

I removed the large plug. Looks like the connector is the black one to the left. Looks like its going onto a plastic box but dont see anyway to ope the box to pull the plug down and out. Any ideas?

Looks like it goes into a box but i cant open it cus there is a metal bar running across the top of the box. WOW. any idea? Thanks again

Hi - my bad - I got the wrong half of the connector. It's the bottom that connects to the rotary switch.

I've attached the JTIS procedure, which also shows the location of two harness clips on the transmission.

Thank you..Thank you. Just what the doctor ordered.

Job done.. No more gear box error. Thanks for your help.
