I need to replace this, I just have no idea what to call it. It’s mounted on the driver’s side inner fender just behind the battery.
Thanks in advance bros.
Get a Ford one if you can
The engineers used to tell us there was a special zener diode inside that the aftermarket ones did not have
You could see this on the SBDS (if it had an aftermarket starter solenoid) We used to think Big Deal but
The Ford ones are only about ten bucks more (availability may be an issue)
The diodes were in all of them not just the ECU equipped fuelliesFlyback diode. It prevents damage to sensitive electrical components by preventing voltage stored in the coil that opens the relay from traveling down to the ECU.
Any relay used on a vehicle should have these diodes. You can tell if you look at the schematic on the side of the relay.
Right side is standard relay showing the contacts and the solenoid that closes them. Left side shows the same but you can see the little side loop with the small triangles. That's the symbol for diode. Left relay is what should be used for something like a fan relay.
Right it's internalLately, I’ve just gotten in the habit of buying Motorcraft because I got burned by other products. So it’s funny to me that I had already bought a new Motorcraft from Rockauto before I saw any further replies after the first. Thanks for confirming my choices, y’all.
Side note, that diode is inside the solenoid, right? No separate purchase needed?

YessirYou just hooked up the wire that goes down to the starter to the wrong side
