K2543 to 24v

Is it possible to use K2543 on old military car -Bombardier Iltis- under 24v ?
Maybe to change few resistors…
Thank for your reply

If it has a negative ground, it should be possible.
The manual features values for 6 & 12V, so it should be possible to extrapolate values for 24VDC.
Please note that this has never been tested.

Thank
I will test & inform you on the result.
