My issue was pin #2 on d3 wasn’t fully inserted (ground wire), got that hooked up and am fine now.

Just did the install today and no luck. I have a 2007 with no indicator light and want to troubleshoot to see if I'm at least the switch to the ECM is working.

How do I troubleshoot this? I saw that some are mentioning that they're testing voltage while depressing the on/off switch. Are you removing the pin from the D3 connector and then using a multimeter to test? I'm not sure how else that would be done. I did pull the pin and checked and am getting 13.3 volts whether I press the on/off button or not.

Update - I found the issue. The splice connector under the hood was not set up properly. Set it up correctly and all is working well.
