Thanks. Is this correct?

- connect self test input to slot 2
- connect run test light to slot 4, and positive battery terminal
- watch the test light, counting pulses that are 2 seconds apart
- code is done when there is a 4 second delay, indicating another code is starting

Does the test light need to be a 12v test light?
