I used OBD Link Ex, it’s designed for Forscan and Ford vehicles.
Thanks. I’m ordering it right now.
I ordered and received the OBDII connector the other day. How difficult is it to get to the BCM? Do you have video or photo of you getting to it? I'm sure I can YouTube it but just asking since I'll follow your instructions on installing the DD fog lights.
It’s on the passenger side toe board real easy to get to.
Under the passenger dash pull out the floor mat and there is a rectangular plastic cover against the firewall. Grab both sides near the top and give it a good yank. Use the crease lines in the carpet to align it back when done.
Ok. Thanks. I’ll take a look tomorrow morning to see what you’re referring to
Hi all, was hoping to get a little help/sanity check. I've added in my Diode Dynamics lights, and I'm running into something similar to this and not sure what's up/am losing my mind a bit. This was a good sanity check since it matches what I'm doing (except for the blue wire for backlight as I'm using that.Hi again all! I got my lights installed today and thought I wired everything up according to my understanding from the write-up, but now the fog lights stay on all the time. I drew the diagram attached and this is how I have wired things. The BCM #6 pin is wired to the "S" Switch Input Wire on the DD wiring harness. The "VB" Positive Wire is connected to the batt/post under the hood. The "G" Ground is connected to the factory ground wire under the hood. I did not connect the "DW" deactivation wire or the "BW" Backlight wires to anything, as I didn't want the running backlights when fogs are off. I made and saved all the of the FORscan changes as described as well and the fog light dash indicator does show when the fog light button is pushed on the F-150 hyrbid headlight switch. Do you see anything I may have missed or hooked up wrong?
Additionally, I tried disconnected the "VB" Positive wire while leaving the "G" ground and "S"-->BCM #6 wire connected, and this results in the fog lights not turning on at all under any condition. Any and all help is most appreciate!
Straight from the DD instructions... Brake pedal and steering linkage visible in photo. Should be something similar on the BCM side if that is your preference.
I assisted Larry with the fog light wiring change today for the Diode Dynamic fog light kit. It was initially installed per the instructions received from Diode Dynamic. The toggle switch was wired and placed under the dash. The F-150 headlight switch, (part number in the first post), was installed, but did not allow us to enable the fog light indicator on the dash or be able to use the push button on the head light switch to turn on the fog lights because the power was not being provided by BCM. He was able to find the correct pins and location of BCM connector through researching other posts that are currently active. He ordered two wires with the correct connector pin, (part number in first post), to add to the BCM connector to power the fog lights. Today he wanted to find the way to connect the BCM to the existing Diode Dynamic wiring harness. The wiring changes were minimal. The toggle switch was removed along with the two existing wires connected to it that ran to the switch input line and the passenger side headlight wire harness. The remaining Diode Dynamics wiring harness was left in place. This was convenient because the front grill of the truck did not need to be removed to complete this wiring change. The two pins, pin 6 and 7, at the BCM are power wires for the fog lights. One is for the left fog light and the other is for the right fog light. We only had to add one wire at the BCM connector because we did not remove the Diode Dynamics wiring harness. This allowed the one power wire to apply power to both fog lights through the Diode Dynamics wiring harness. The new wire from the BCM was connected to the switch input wire that had been connected to one side of the toggle switch that was removed. That completed the wiring changes for his fog light install today.
We moved on to the Forscan changes that allow for the fog light dash indicator to work. Two modules are involed in the required changes for his 2023 Ford Maverick XLT. I will list them separately.
IPC Module
Front Fog Lamps (default is disabled) - Change to enabled
BCM Module
Fog Lamp Usage - Fog Only
Front fog lamps - (default is disabled) - Enabled
Fog Lamp Switch (default is not available) - Available
Fog Lamp Switch Type (default is hardwire) - LIN
*Left Front Fog Lamp Usage (default is not used) - Fog only (providing power from the BCM)
*Right Front Fog Lamp Usage - Not Used (We only needed one power input since the Diode Dynamic wiring harness was ran to both fog lamps.)
*We initially used both the left and right option becasue we could not remember which pin we chose to use to send power to the fog lights from the BCM. After we tested that everything worked, we disabled the pin that we did not install a wire into during the wiring change.
The fog light indicator is now working and he can use the push button on the F-150 headlight switch to turn them on or off. The fog lights automatically turn off when the high beams are turned on. The amber back lighting is working correctly. The Diode Dynamic fog lights, custom wiring and F-150 headlight switch give his truck a factory feel.
The way most people have been wiring it, that BCM wire is the actual 12VDC+ power for the light(s). The LED fog lights are a small enough load that the BCM will power them. After programming with Forscan, all the F-150 switch does is digitally tell the BCM to send power out that new wire.
