I am new to this. I joined because I couldn't find info elsewhere on my Highlander. I am installing a GPS and need to connect several wires some of which no one seems to know where they connect. The wires are parking brake and illumination. The wires connect to a Pioneer AVIC-D3. I looked under the dash and can't see a parking break switch. Is it there or under the hood somewhere? I have no idea where to connect the Illum wire. I assume to the dash dimmer switch but not sure.
