Savage XL conv. problem with Reverse module

Ok, here is what I do:

Ch1 is of course steering. Ch2 throttle. Only forward makes sense (on the ESC I enabled only forward mode). The brake servo is using Ch3! So it is mixed with Ch2 on the transmitter. In the car, the HPI mixer 'listens' to the brake servo (or ESC signal) and activates the reverse servo when the brake has been activated for 3 seconds.

So, it should only be able to switch to reverse after full stop - brake for 3 seconds, not just when doing releasing the throttle or doing a quick brake.

Can I wire it differently?

after your last post and re-reading the first post it sounds to me like the reverse mixer is engaging after 3 seconds of throttle, rather than 3 seconds of brake.

it sounds like you need to reverse the servo direction on channel 3

you could also just run a y cable and use the esc and brake on ch2 and use the 3rd channel independently (without a mixer, that's a kitchen appliance) to shift the reverse servo
