In my 62, the housing for the 4WD indicator light has an opening for a second light that's taped off from the factory (also the indicator light window is blank), along with an unused socket for a 194 bulb. It gets its power from the 4WD indicator circuit (yellow wire) but grounds through a green wire with an orange stripe. Obviously it wasn't meant to be used in this truck's stock configuration, so I assumed it would've been the diff lock indicator for non US models. A quick look in my wiring diagram told me that's not the case. Also looked for any leads in the diagram using a gren wire with orange stripe and found nothing So I'm curious, for any of you who have an non US 62 or maybe an HJ61, do you have an indicator light adjacent to your 4WD indicator? I looked into the harness itself and the ground lead is also connected to the larger white connector that connects to the vehicle harness, but no clue where in the vehicle it goes from there.
