This procedure is for cars with Daytime Running Lights (DRL) only
The foglight procedure may work in Non-DRL models, let me know if it does.
The goal was:
A) Allow foglights to run independent of headlights
B) Bypass DRL to allow foglights to be used instead
Foglights in DRL CX-7's are wired to the Low Beams. If we instead connect them to an ignition accessory (such as AC) they will run when the ignition switch is ON. We have to bypass the Auto Light Control Module (ALC) or they are still shutdown by the High Beam switch.
DRL is turned on by releasing the footbrake with the ignition ON. This runs the High Beams at 50%. To bypass DRL, ground the ALC wire which monitors the Parking Brake switch. This must be done at the point where the wire Just enters the ALC. Grounding it at other points will interfere with the Brake Lamp, Navigation, and possibly other car operations.
This is the original circuit for DRL headlights
