You can buy color coded links at most local auto parts stores.
Dodge recommended splicing them in on the other side of the fat multi-splice. This asumes you are comfortable with soldering.

This is prob a correct color identification for your truck's links if you can't find any other ref.
Color Wire Gauge of Link
Black 12
Red 14
Dark Blue 16
Grey 18
Orange 20
White 22
Whether the colors available in the store will match, IDK. Important thing is the link's wire size.
