  1. Does anyone happen to know the part numbers for the BCM - X5 (Brown) connector? I have the OEM part# (13826916) and Service part# (13576034), but expect the connector to be TE or JST but cannot find the part numbers or for that matter the connectors in any fashion.

It seems odd that there is little reference in the manuals or schematics referencing a fuse or relay for these things. The come on at dusk when auto is selected so there must be a relay connected to them, or at least a fuse that can be pulled. In the schematic "Sierra 2500HD Body Builder" there is a reference to a relay KR53 but I do not see this referenced in any fuse/relay box. Oh well, I will keep digging until I find it.
  4. I have searched this forum and Googled myself to death and have not found the right words to get any results to suggest which relay or fuse is used disable the amber cab marker lights. I would like to put a separate relay or simply a switch in series with the fuse to be able to darken all the amber marker (mirrors included if possible). California says it's illegal to run these cab markers and want to be able to selectively turn them off. I have not been able to simply identify the relay which controls the markers at dusk, suggesting a relay is in the circui
