Gentlemen,
A customer would like me to hookup his heated seats to work with
the Ultrastart 3265 I am going to install for him.
How do you interface with them in a 05 Durango?

you'll need to isolate the wires going to the heated seat button(s) and then use your status (-) output to trigger a relay that grounds on of the wires off the heated seat button through a resistor -- I do not know the resistance you'll need to ground it through, but someone else may and can chime in.

About what I thought - thank you. Correct me if I am wrong but I should be able to test resistance of that wire to ground and come up with the value. I am assuming I will have to diode isolate to prevent back-feeding from one switch to the other. Anything else I may be missing??   Thanks, much!

with a good multimeter, you absolutely can test the resistance when the button is depressed -- should work to find the resistance, best of luck, and lemme know if i can help out further.  Also, you have a couple choices, you can use an auxilliary button wire (-) to trip this relay, OR you can use the status output wire to trip a latched to momentary relay that'll emulate a pulse (-) to the heated seat button.

So the heated seats have their own "timed" latch?

I dont' recall off the top of my head if the Chysler/Dodge heated seats are push button latched or push on/push off or rocker style switches ..

If they are not rocker style, then yes, they have their own timed circuit, and all they need is a pulsed ground via a specific resistance to activate the circuit.
