Hello,

I would like to install a DEI 545T in my '04 Dodge Ram SLT QC.  I know the Rams have multiplexed wiring using resistance to ground to make thing come on, but how would I connect the 545T?  I would like to have the headlights and parking lights as well as dash illumination come on when dark as well as when wipers are on.  I found a little info elsewhere: cut purple / YELLOW at headlight switch, 87A to switch side, 87 - 470 ohm to ground, 86 - ground, 85 - +V, and 30 to vehicle side.  There is no mention if this is for the 545T, but seems to be, and I don't think this includes parking lights either...please help!  I don't have any type of alarm/RS installed, I would just like auto headlights.

The parking light wire is multiplexed. 270ohms is parking lights, 470ohms does headlights.
