Power inverters

A few years back I removed a power inverter from an old 69 Superior donor car. For some reason, I did not get / can not find the electrical outlets for it.

I found some old 2 prong black outlets with the black face plate, but I wonder ig it is what was used in the cars at that time or did they had specific outlets/face plates that they used in the ambulances.

Does anyone have a picture of the electricale outlet and face plate from theur coach I could use as a reference?

Thanks,

Most that I remember were the two prong style with chrome face plates. The three prong style became popular much later.

Jean-Marc, if no one posts any I will take some pics tomorrow.

This is from my 75. My 57 and 76 both have invertors with simple plugs (just like a wall plug, two prong of course in the 57) and no switches. Hope this helps.

Thanks Tim. These would be located on the driver side close to the back door?

Thats the spot
