My turn signal switch broke again,find out it does not like when i hand force it to cancell example switching lines and only need few blink.
Found this page:

When i checked my steering column components turned out the different hole location is there.

So just need to find the correct switch.

Sadly, all the cheap switches have the lever angled the wrong way. I need the straight one, which is one of the more expensive types (about $50–60).

Another important thing is the hazard switch on the left side. It's very tight and can possibly cause the turn signals to stop blinking — either when braking or not blink at all. So, file off as much as you can to make it fit and move more freely.

Actually, I started with the wiring because I wasn’t sure if it would work at all. So I asked ChatGPT which wires to connect to the Mopar harness — surprisingly, it was pretty accurate.

So wiring colors:
Mopar GM
dark green - yellow
white - white ( brake switch)
brown - green
black - black ( horn )
tan - dark blue
red - purple ( flasher )
light green - light blue

It only took two days to figure out why it worked when wired together, but not when installed.
Easy peasy. :)
 
A GM switch in a MoPar?

You must have a tilt column, then, because MoPar only used GM Saginaw columns whenever tilt columns were installed otherwise the car should have a MoPar column with a MoPar switch. If it's not a tilt Saginaw column did someone convert it to use a GM switch??
 
No tilt column it's a 68' Monaco and i pretty sure never been modified before.
I think all the column components were made by the same company, which is why they are very similar, with only minor differences.
