Hi Tony,

Thanks.

I just noticed something verrry interesting also, as Arte Johnson playing a German soldier used to say in "Laugh In" for us baby boomers who remember it.

Comparing the early brass light switch plate with my later steel switch plate I noticed the early ones will only switch on the designated light as compared to the later ones that switch on combinations of lights at two of the switches: Tail and Side" and "Tail Side & Head".

This sure makes wiring simpler for earlier trucks as almost any automotive single pole single throw (SPST) toggle switch could do the job.

The later version requires the special switches that can only be described as triple pole, single throw with common input side. The outputs terminals are all isolated from each other in order to allow the lighting combinations to occur. If they were not isolated from each other, any switch would turn on all lights!

No doubt others have noticed this but I though it might make interesting reading.

Cheers,
