I purchased a pre 06 ballast switch plate( bertha ballast) from a dealer going out on ebay. then i ordered the triple ballast wiring harness from my dealer 06 to 08. the switches are the same, the harnesses match up perfect for all colored wires except for the top left RED wire, wiring harness has it, switch plate does not.
Any idea where that red wire goes on the ballast plate?
i have also enclosed the 08 and forward switch plate for comparison.
