The R/R/LG/LG four-wire (it's actually a six wire bundle but two aren't used on the diesel) is your CLUTCH INTERLOCK SWITCH and is wired to a connector which goes to the under-dash clutch assembly. The R (Red) leads are for starter control, the LG (Light Green) leads are for Stop Lamp Switch to Turn Signal Switch
The R/R/DB (Red/Red/Dark Brown) three-wire is your TRAILER TOW RELAY and normally would have a female plug .
It is the Ford Electrical & Vacuum Troubleshooting Manual.
This is a great book (by year and line) that you can often find on Ebay for $10-20
It breaks out the wiring and vacuum lines into discreet circuits and outlines testing each component.
Every harness splice is shown.
Pinouts for all the plugs.
WIRES???????
