Very E-Z!
jkalchik - said it all!
Best & easiest is to get the "brand specific" wiring harness which is often included in the Prodogy purchase "deal".
Not expensive if you don't already have it - and it's nicely
wrapped (no loose wires).
[Well worth the couple of days wait for a parts supplier
to mail it to you]
With it, you DON'T need the wiring harness Dodge gave you
-or- the "generic" harness that came with the Prodogy.
No matching colors, no crimping, no soldering,
- genuine "Plug & Play"!
Remove lower dash panel (two metal screws at bottom,
pull out at top) and you have access to everything.
Insert plug into mating connector (to far left of steering
column over towards the parking brake - by pack of wires -
pale blue in color).
Plug other end into controller. Done.
