Hi,
I am planning a project to intrude to the ABS circuit in my car. Basically, to operate a 5 pins relay whenever the ABS in engaged (i.e. the ABS motor is in operation). The ABS motor circuit is shown in this figure attached. The other figure shows where I might insert the relay (just near terminal 16). My questions are; will this setup work, is there enough power to operate the ABS motor and the relay all together, will this setup cause any damage to the ABS circuit and actuator? Note that I can only intrude to the connections outside the ABS unit (i.e. terminals 17, 16, and 19).
I am planning to use a relay similar to one shown **broken link removed**
Is there any other cheap way to sense if the motor is running or ABS is in operation. (Note: the ABS assembly is located in close proximity to the car motor).
