DIY Cruise Control FAQ (2006-2010 Yaris)

[CB900F2]

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
