ID two threaded bolt holes: driver side of engine room (inner fender)

I will post a picture soon, but while running a harness for an LED bar I noticed two unused threaded bolt holes on the driver side inner wall of the engine room, i.e., the body wall next to the battery. That would be a really useful spot to install a little cable holder for this big ol' harness.

Does anyone know what size bolt these threaded holes accept?

I have a V6 2WD SR5 w/Tow. Maybe these holes are for something related to 4WD, the most premium Entune system, an OEM security system, or manual trans.

 

Have a pic?

 

I will soon. Thanks

M8x1.0

 

Could also be m8x1.25

 

I believe it is for something on the standard models. Something to do with the clutch. I used those holes to mount an auxiliary fuse block. I asked on here before and got an answer but can't remember what it is now lol

 

M8, 1.25 pitch.
