Can you identify this hazard switch?
 

It is on a 64 and it looks like it says 105 in the center and maybe the chevy emblems are smudged off, but it looks like the center is pushed in and I thought they were rounded like in the 2nd picture I attached. I am trying to find out if this is original Chevrolet first and if it was correct for my 62 second.
I attached 3 photos. The 1st photo I am trying to decifer what it is? The 2nd photo shows the 105 and the 3rd shows no 105. What year did they start adding the 105 in the center?
Thanks for the help!

Hi AJ,

I'm not real familiar with how the knob styles on those hazard switches changed over the years, but I can tell you that the turn signal wiring changed to a different style switch & plug in 63.

If your 62 has the original steering column and turn signal switch, it'll likely be a cable operated setup with the electrical part of the switch mounted down on the under-dash part of the column. And it'll have sort of a pyramid shaped 6-wire plug.

The 63-up columns have the turn signal switch in the upper part of the column and use two semi-circular shaped 4-wire plugs like the ones shown on the hazard flasher in your 2nd pic.

A 63-up hazard switch could be adapted to the 62 wiring, but you'd need to find both a male and female set of the black plastic terminal housings with the pyramid shape that fits the 62 switch/wiring.

It's not noticible once installed, but there were at least a couple different designs hazard flasher switches used in these trucks. The early style has the flasher module mounted on a separate bracket under the dash (using one of the same screws that mounts the switch bracket). While the later style (started sometime around 64) has the flasher module right behind the switch.

If you need help wiring one up here's a link to wiring diagrams for the 60-66 trucks:

The first one is also a 105 .. red knob screws on the same as the others .. and the case should also read 105 and probably have the 63-66 connections .. I have one simulair to the 3rd one pictured on my 62 truck ... Took it off my 62 suburban before it was junked , just sold one like picture 1 .. out of my 66 truck .. I have another style one that was put thru a hole in the Steel part of the dash also , not like any othe pictures shown .. But have seen several ..

My 63 came with the 105 hazard light from factory

The one in my '65 has 105 only. No Bowties. It's original to the truck.

not to change the topic but since we are on topic of hazard switches the one in my 65 in nonexistant but the truck was a very low optioned base model. did all trucks come with hazards?
