I just installed my PAC AAI-NIS2 today. However, after connecting the new harnesses provided with the PAC to the head unit and then the old wires back into the new harness, after turning the radio ON, it only shows "No Signal".

I verified that all the wires were connected and connected my iphone using a RCA to 3.5mm cable.

Did I miss anything in the installation? Thanks guys/gals for your help.

 

Nevermind, it looks like I should not have used the 12-pin connector in the first place.
