1969 Belt and Park warning lights

[asrassoc]

Lucked out and found wiring harnesses (i think) and bezels for both.

Some repairs to the wiring but all appear to be functional. 

Question - the three harness i have each have a different colored end at the bulb socket. RED - Belts light (has the relay wired in), Green and yellow - for the Park break warning light?

I know there were at least 2 more warning lights (Fuel and Door) of similar construction.

Does the color of the bulb holder signify anything?

I only have the Park light. It is the yellow socket with a green and a black wire.
