on/off switches for convoy lights and spotlights

[juanprado]

I have 2 light switches off a m936 parts wrecker that are on/off switches for the convoy light beacons and for the floodlights.

I am trying to wire them up to use. The back rubber housing has 4 wiring connectors. They have no numbers or markings except 2 have ribbed lines and 2 are smooth. See the pictures.

I assume they ground through the mounting.

Which side is the hot supply side and can only one wire be used? lined ribbed side or smooth?

The other side would be 2 hot switched feeds when turned "on"?

Thanks for your help!

What are the numbers on the metal tags on the wires still connected to the switch ?

An ohms meter would be your friend!

all 4 are #87 for the floodlights but I do not know which side was hot and which side went to the lights?

smooth, switched output.

Use an ohm meter to confirm.
