Looking for Mazda i-Stop Eliminator

[Yo'sDad]

Sorry, but that's not how it works (at least on my CX-50, and I've no reason to think the CX-5 is different). The buttons are just inputs to a microcontroller, which sends commands via a serial interface to the BCM/ECM. The istop 'dongle' actually connects between the switch unit and BCM/ECM and sends the serial commands itself.

It might be possible to solder wires across the switch on the PCB and exit them from the unit, but the switches are surface mount and the contacts very barely exposed.

For more detail on my CX-50's switch/PCB/unit, see:

Permanently Disabling iStop - an installation how-to

On another forum, there was a discussion some time ago about disabling iStop using a 3rd party plug/play unit from mikstoreph.com. I searched the web for how this worked, and it seemed, from a couple of pages I saw (below), that the I-stop button is just part of a resistor ladder along with the...

THanks, so you are telling me that when you push the istop button it sends a code to one of the controllers and is not just a simple closing of a circuit? Wow, why is it necessary to design something so complicated for such a simple task? So happy I don't have such a model. I suppose someone could attach a solenoid mounted to the button that automatically pushed the button each time you started the car, haha.... just kidding, but it would work. Or move the button to under the dash and have a rod activate the button each time you pushed the brake pedal down, as in when you start the car... now I'm getting out of control... need another beer, haha.

Just consider it an item on your pre-flight checklist. It's not that much trouble.

Yes, correct. Because it allows them to use just 4 wires (power/ground/sig+/sig-) to support up to five buttons and two indicator LEDs, which would otherwise take at least 8 wires. So, wiring weight and space/complexity savings (I presume).
