Viper 4806V, 2016 International 4300

I'm focusing on the remote entry to start. I believe I have all the remote start wiring figured out. Here's what i have for electric lock wiring on my truck. I purchased a 456l thinking that would work to communicate with my system but it is a single wire system and i believe i have a dual wire system. A little help would be much appreciated.

This truck is a 2016 international 4300 with electric locks but no keyless entry.

Looks like they're using a data bus network. You either need a data bus interface or you'll have to do a 5 wire setup to both door lock motors. I don't know what data interfaces are available for heavy-duty trucks if any. Maybe someone else knows.

Yah I haven't found an interface module besides the one from international which runs a couple grand. One thing I have learned is the switches in the door "pod" that you push down to initiate the lock or unlock are completing a negative circuit inside the circuit board. Would it be easier to solder my wiring from the viper remote entry system to the output side of the switches in the pod then do a 5 wire setup in both doors? I feel like this would allow a smaller amount of overall wiring.
