just so you guys know my local Ford ordered a bcm terminal with pre installed cable for a low $9 so i can setup accessory relay for dash cam or uhf setup if looking at options.
as informed by Stewart different terminal to drl mods

Pretty sure part number is DU2Z-14474-DA. Possibly confirm once you have it for others reference as it will come in FoMoCo bag.,

You'll need to pull the plug on the BCM, dismantle it and fit the terminal pin, then reassemble. What you'll end up with is a single wire that has a 12v signal with ignition, which in turn can be used to feed a relay. There are instructions and pics somewhere, not sure where... if I find them I'll post a link.

cool got the part from Ford as described.
run in cable but need to source dual load relay first before connecting to bcm plug.
dose the relay need a resistor or diode to prevent voltage spike during contacts potentially sending voltage spike back to bcm?
only see a dual 40a which is overboard for a dash cam, uhf.

No. That is the whole idea of using a relay in the first place. BCM is only triggering the relay coil and is isolated from any other voltage source if wired correctly.subzero747 wrote: ↑Tue Jul 16, 2019 7:14 pm cool got the part from Ford as described.

If you are only powering a dash cam and uhf I also would not even bother using a relay, the current draw would be no where high enough to be needed.
