Hi All,

I purchased my D3 from Crutchfield and adapter 70-2003 was included for my '03 Toyota Matrix. I noticed there are two wires from the adapter: Orange - Illumination & Orange/White - Dimmer. However, from the Power Cord of D3, there's only the Orange/White - ILL ... I'm not sure which way to go with: 1) Dimmer with ILL because wire color matches, or

2) Illumination with ILL because they are both for, well, illumination. Any input is greatly appreciated, since I'm going to install it this coming weekend. Thanks!

some cars have negative dimmers. test both wires and see which one gives you 12v when the lights are on, thats what you need

That makes sense.

Thx again, Misfit!
