Normal Operation - Halogen Low Beams

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

When the smart junction box (SJB) receives input to turn the low beams on, the SJB provides voltage to the LH low beam through circuit 1338 (WH) and the RH low beam through circuit 1336 (LG/WH). Ground for the low beams is provided through circuit 1205 (BK).
