Good afternoon, I am in the middle of the install and would like to know if anyone has the climate controls working on the Pioneer. I have a 15 Optima EX w/out nav, no amp, and it's not infinity. All of the harnesses are from Idatalink. When I received the harness the twisted pair on the harness for the ODBII connector was connected to a yellow two-pin connector so Crutchfield helped me get that resolved. So now I am at the last part and need to know what wire would connect the climate controls to the Maestro RR. The buttons in the head unit are grayed out. Idatalink shows the climate controls will work with this setup. Any suggestions would be greatly appreciated. Thanks in advance.
