Default Re: Run-Start Circuit Failure Leads to Top Nonfunctioning

If anyone knows what outputs may be sourced from pin 58 internal to the BCM that would be helpful.

Have you downloaded the service manual and perused the BCM system circuit diagrams? The pinouts will locate the circuits for you, you can build from there the answers to your questions. Looks like quite a few pins are effected. The manual is free to download and available with a search of the site. Good luck!
