Hi david, The 1966 Factory Service manual is scanned and in progress to be added to the site. There are a number of folks working very hard to continue adding more content to the IML web site. The scanned pages are available here ; http://www.imperialclub.com/temp/FSM/FSM/1966%20FSM/ Just without the pretty interface and web page. Page 226 seems to be the page you are looking for here; http://www.imperialclub.com/temp/FSM/FSM/1966%20FSM/1966%20FSM%200226.jpg Looks like the wire colors are B L & H You may have to snoop around a few page numbers from there to get all the info you seek but the entire manual is there. Best of Luck, Jeff Ingraham IMl Volunteer > From: David Whitney > To: mailing-list@xxxxxxxxxxxxxxxx > Sent: Wednesday, June 27, 2007 9:48 PM > Subject: IML: '66 auto headlight dimmer wiring -- > 2nd request > > > I have learned from another mailing list that the > three wires from the dimmer controller are > distributed thusly -- two to the headlights and one > to the headlight switch.
