AD4 is under the top of the dash. You have to remove the dash top to get to it. Also, the wire from the ECM to AD4 is only there in 2009 sedans and 2009+ Puerto Rico cars.

Hi Scott.. Maybe we Canuks are lucky in this case, my 08 Sedan has the wire at the ECM, and I can only assume it connected at AD4

I had to confirm and took apart the ECN connector and snapped a photo..
Like you indicated, it appears that there is no access to the AD4 connector from under the dash, but wonder why Toyota/Rostra would put out these instructions if it was not possible?

Maybe to mess with our Cruise Control crazy minds :p

You just need to train a rat to climb up there and plug the pin in for you.

I think that should not be a problem, Toyota dealerships have many of those, I think they call them "Automotive Technicians"

I thought you did an excellent job with it. Now, we just need one for the 2008 and older cars that require the ECM and steering column pins to be added.
