Bill,
Start by accessing the wiring diagrams in the BAC Coach Assist section. Log into the Forum, click on Home. Then page down to the Private BAC Members Only board. Select it and click on the Link to Coach Assist post by Tim Bentley. Click on the link in his post and you'll be able to select any of a number of wiring diagrams. In many cases there is little difference from year to year so you may find the info in a wiring diagram that is not for your exact year.
Good Luck, Steve
