I'm trying to determine the ACC/RES pin on the Cruise Control ECU, I know it's a long shot, but does anyone know which pin it is?

I did find info on the SET CRUISE and CANCEL, and brought it all together in one image:

Location of Crusie Control ECU (Be aware, these images are number backwards, should be number from left to right when looking at module):

Solution
The control switch uses different resistances to signal what it intends to do. Let's forget about wire colors for a moment; between the two pins:

-In the switch's neutral position (OFF), there should be no continuity; all of the below paths are normally open.
-When moved to CANCEL, resistance should be about zero ohms.
-When moved to RESUME, resistance should be about 820 ohms.
-When moved to SET, resistance should be about 2700 ohms.
Does anyone have knowledge about how the cruise control lever operates on the steering wheel, specifically about the signals for it's two connections? I'm assuming that the switch shorts to ground, but it only has two wires yet 3 positions. There is a yellow and black wire coming off the switch, which connect to a blue and black w/ white stripe wire going to the clock spring. Also exit clock spring as blue and black w/ white stripe. black w/ white stripe I believe goes to pin 18 on cruise control ECU. Could cancel be both wires shorted to ground at same time?

Exactly what I needed, thanx mate
