OBDII mobile tracker: Reprogram to have one of the pins throw a positive or ground? I am not using in a auto, just want to use it as a remote switch to operate a 12vDC 125ma device.

 

Do you have any documentation describing the circuit and firmware?

Most likely you would have to make something that looks like a diagnostic port to plug it into and then the OBDII would communicate with the port.

 

Here are links to: a user manual, port plug, and standard PID for all OBDII's.
Note: I am not partial to this model, I will buy any model tracker if you recommend a different brand.
I am working on getting the firmware.

User manual

Female plug

Standard PID (see Hex 65 in chart: Says Auxillary input/output, so I hope it can throw positive or negative to control a 12vDC 125ma device.)

Standard OBDII pin layout attached.

Thanks!
