Thanks so very much for your effort. This is the first time I have seen information regarding the identity of the BCM connector interfaces. I do not have a service manual so relying entirely on the wiring diagrams provided by mooseman. Maybe the BCM fully documented in the package provided by mooseman. I never checked that, my oversight if that’s there. Previous to your reply, I had no idea as to connector identification or location.
