05 ram 4x4 slt reg cab short box

Im getting ready to do the two front bearing hub assemblies. Little confused on the abs situation.

i have a wire going to the drivers side front hub. No wire going to the passenger hub. I believe this means i have 2 wheel abs.

speaking in terms of moog part numbers, there is 515072 which is for 2 wheel abs. I went into advance auto and saw that there is no wire on this hub. Moog also has 515073 which is listed for 4 wheel abs. Pictures show this part having the wire.

my question is if im doing both front hubs do i need 1 of each part number even though the 515073 says its for 4 wheel abs?

 

I think the PCM uses the left front speed sensor for both the speedometer, and cruise control. So, I would expect one of each.
