the bit that makes the hazards come on after a hard bump is in the 10as unit not the crash switch, had a slight off last night in my challenge buggy & the hazards wouldnt stop flashing no matter what i did, i have no flasher relays & no crash switch, traced it back to the 10As & as my ecu has the immob removed ive since junked the 10as & no hazards flashing now,
to give an idea of the impact i landed in a drainage ditch @ 40mph to a dead stop nose first,
