I need the part or size for the PCM relay for a 2012 F150 XL Supercrew with the ecoboost engine. Should be position 10 in the engine compartment fuse box.
I've looked quite a bit and I can't find the size for this one.
Bought a truck at auction and its missing completely. Can't wait to see what other surprises I find when I put it in.
Thanks!

 

Looks to be the same as #40, the one right below it. That's the electric fan relay.

 

Not on my truck. The PCM relay has 4 pins/blades on it, and the fan relay has 5. The PCM relay spot is also a little bigger.

 

Are you certain of which engine the truck is equipped with? What is the 8th digit of the VIN?

That relay is only installed on the 3.5L EcoBoost version. It's supposed to be empty if the truck has any of the other engine options. I'd be surprised to see an XL-trimmed truck with an EcoBoost installed.

Does it start and run or was this purchased as a salvage or otherwise non-operational truck?

 

Its ecoboost. 8th digit is a T. Its not cranking. Hooked up 2 different code readers and they both could not connect to the pcm. Opened the hood and looked and found the pcm relay and the one below it missing. Can't wait for the surprises when I get it in.

 

For completeness...

Thank you!
