Immobilizer

[BOOTLEG]

Car arrived with dead battery that had no response to my charger. It was also full of water which I have drained. I am using another battery which is too small so the cables don't reach the posts. So, my battery leads are #10AWG which cannot handle starting current which is why I don't want to try starting it. However, I would still like to determine if my IM is working, hence my question. B/C I have lights, signals etc. if I knew if these functions were controlled by the IM, I could move on in my punch list.
