2003 Dodge Ram Cummins Diesel

DEI 561-R remote start system.

There is no wts wire on these trucks. I have read or heard that the wts can be triggered off of the block heater itself.

How can I do this? Just hook up the wts wire based on the polarity that I see from the block heater?

Is it really that simple?

My wts light is only on for maybe 3 seconds. The system currently waits 15 sec before it starts.

Is it possible to tap the glow plug wire then add 528t timer set at 4secs.?

These trucks don't have glow plugs, they have a heater grid. It has a big honking wire going to it right at the intake. I would like to attach the wts trigger wire here and as soon as the heater goes off, have the truck start.

I put this same system on an 01 Dodge diesel but it had the actual wts wire I was able to tap into. These new trucks use a bus from the pcm.

Ignore remote's starter output violet?), remote's first ignition output, pink (?) to BLACK/ white of 528t, cut loop on 528t, red and yellow to constant 12v+ via a 20amp fuse, cut brown, black to ground and orange to vehicle starter wire, add a relay if two starter wires, set 528t for 4 secs.

CORRECTION! Use 561 status or GWR output, to BLACK/ white, don't cut the loop, wire the rest as above. More fail safe.
