K2599 wiper delay in combination with 2001 Mazda Mx5

Hi people,

My MX5 has three wiper functions: INT, I and II. Since I’m not happy with the non-adjustable INT position, I was hoping to get more flexibility with the K2599 module.
There is only one problem: it looks like this module can only be used with cars that only have a I and a II position…
When I check my wiring I get:
Blue-always ON
Black-ground
Blue/white-ON in I and II
Blue/yellow-ON in INT, I and II, but OFF in ‘zero’ position of the wipers
Blue/red-ON in INT, I and II

Is there a possibility to get this working?

thanks for your effort,
regards,
Cor
