S197 3V What is this panel/box in the engine bay?

[Motonoia]

I am checking out early S197 Mustangs and I came across this 2008 GT that had this panel/box in the engine bay. I didn't see it on other GTs that I saw. Does anyone have an idea of what it is?

Possible the fan relays, they moved them out of the fuse box around 2008 to 2009,

05 to 07 coolant issues

Hmm, not sure that’s accurate. I think the fan relays are in the fuse box for all years. Common modification is to bypass the factory relays and install external fan relays. The stock relays, contacts, wiring, and fan connector are known failure points for the S197 and the circuit is often bypassed with an external circuit. I did this in my car.

I have a 2008 Mustang GT and my car doesn't have anything there. There are two spots in that location where you can attach something, but nothing was there.

I did use that location to mount the relay for the water pump that I installed with the DOB supercharger.

By 2 spots, I assume you mean two holes? Sort of like what is seen/shown here? Its interesting that some cars I am looking at have something there and some do not.

Historically, that is where everyone moves the fan relays after removing them from the fusebox. That is explained in the link.

Yes, I believe they use 6mm bolts

It's weird to see some GTs have these holes and some don't. I wonder if it was a common dealer add-on of some sort that the holes ended up in the same places in the cars that do have the holes. I guess I won't worry too much if there are holes and no equipment present when I make my purchase.

You'll definately want to investigate the fuse box and consider the cooling mods, not just the electrical one.
