It's terminal 12 in the Bentley 240 manual for WOT (LH 2.2).

You might also want to check TPS idle contact from terminal 3, since the input to 12 is a straight wire (for the test), while the input to 3 depends on adjustment and contact closure.

You've adjusted the TPS, but I'm thinking an idle contact problem could be causing both the idle problem and the failure to close the IAC with the test lead.
