2001 Dodge Ram Keyless Entry

I am trying to hook up my Impulse IMP-4040.  Alarm, Remote Start, & Keyless Entry.  Everything is working but I don't seem to know how to hook up the keyless entry.  I know it is 5 wire reverse polarity.

I have one 451M, do I need two.  Also, are all of the wires I need located in the kick panel in the plug that leads into the door?  Also can the wires be found elsewhere?  Central Timer Module to the Right side of the steering wheel; If so what does this look like and where is it exactly?  About how many wires?

Thanks in advance for any help.

I usually wire at the Driver Kick panel
