Hazard light switches

[Henk]

is there a functional difference between the switches?
I mean, some swithes have illumination and a flashing mode if pushed (this sometimes requires extra pins)
or are the both the same in this regard?

Both sides have a different inside. I mean, when flipped different connectors are "on". Together with 7 pins on one side and only five on the other side. btw the 5 pins are all "on" when the switch is flipped. Looks like the hazard system is complete then. But then there is no indicator system. Same problem occurs when this side is used for indicators. Then there is no hazard system. And like i said, once i had the control lights from battery and oilpressure with the red hazard control light.....

like david and thotos said:  a switch with that many different unknown pins needs a decent wiring diagram and a multimeter.
Haynes is no good, did you check olyslager vraagbaak?

Henk,
 
I have almost every book available about any 131. However, i have no reach of them. Thought it would be easier to ask aroud here  if anyone had ever made this change. Seems i am the first one...for now.
