1985 Corvettes have a one year only MAF Burnoff module which is mounted behind the breadbox. Not easy to get to. When I replaced mine, I mounted it lower for easier access in the future.
1986-1989 Corvettes have relays easily located behind the battery.
Here are some pages from my 1985 Factory Service manual.

Are you having codes/ issues with your MAF?

The 85 Corvette (and TPI Camaros and Firebirds) have the one year only MAF Burnoff Module.
There are no MAF relays in 1985.
1986-1989 Corvettes have relays instead of the MAF Burnoff Module. The relays replaced the Burnoff Module.

FYI: I would avoid Corvette Mods. I had a very bad experience with them. Many Forum members have had bad experiences as well. I encourage you to do some searches on the forum.

Default Harness

The original harness has a relay called MAF POWER on it. Its just been loosened and detached from the engine compartment. Its tethered with the fuel pump relay.

What are the wire colors on the connector that you say has that 'relay' plugged into?

***The last time you asked about those relays I mentioned posting part #'s and 'wire colors' - you didn't!

***Your thread: https://www.corvetteforum.com/forums...post1604420487

You have the wiring diagrams they're there!

If it's actually an '85 harness this I believe might be correct!
