I did a search for seat heater hookup but did not find one for '04 dodge ram with cummins. '05 has different wiring and module than '04 https://www.the12volt.com/installbay/forum_posts.asp?tid=71229.

So, whats the proper way to activate the seat warmer for '04 truck (build date 08/03 if that helps).

Thanks!

behind the switches on the dash, pass. seat : Lt. GREEN / WHITE Drivers seat, Lt.GREEN/ dk green

With an aux out from your unit, send a POS(+) pulse thru a 120ohm resistor, this will turn the seat on HIGH, or if you prefer, thru 250 ohms for low. Hit the aux out again, and the seat should turn OFF. Use relays.

You need seperate channels for each seat, you don't want to do them with one channel at the same time. THE ENGINE MUST BE RUNNING FIRST !

Then it would mean pin #6 of the connector (both switches)? Will use DPDT relay for this (one input for two separate circuit at same time). Will the indicator light come on? Just wondering.

Thanks for your help K.T.M.

The astro chart does NOT say if the indicator light comes on?
