I previously had a C6 Grand Sport so I'm familiar with the rear battery location. I replaced my ZR1 battery yesterday since I purchased the car 3 years ago. I notice this "extra" piece on the positive connection that I don't remember seeing on my GS. Is this a ZR1 thing?

The car doesn't have anything extra electronically that I'm aware of, no aftermarket head unit or other stereo upgrades except someone added a rear camera to the stock unit.

Pretty sure it’s for fuel pump since these cars have a controller for them

Not on my 2011 C6 Z06.

My 2010 ZR1 doesn't have it.

My 2011 has it. It is factory, whatever it is.

Texas thunder strange my 2010 has it

Colonel

My bone stock 2011 ZR1 has it.

Texasthunder

Well shoot. Now I'm going to look at mine when I get home from work. I don't remember it from when I changed the battery.

My 2009 ZR1 has one.

Texasthunder

CORRECTION!! Went home last night and looked at mine and it does have it. Thanks OP, now I want to know what it's for.

Colonel

My 2012 ZR1 Centennial has it as well.

So......WHAT DO IT DO?!?

For battery tender I’d say

you have to look under the carpet. Mine had it but I only noticed it when I took the entire carpentry out. Mine is an 09 zr1. I suspect they changed the location at some point to make it more accessible

As Ravenrider stated it is a fuel system mini fuse.

Just a little side note here a little off the OP's question. Had my 2010 stock ZR1 for almost 5 years till I sold it last year. Unique to the ZR1 compared to the Z06 for instance is the factory limited charging voltage to roughly 13.8 volts compared to about 14.6 for the Z06. I can tell you over time that voltage falls short of what is necessary for full charge and longevity. My specialty was marine 12 volt systems where people depended on them for all onboard systems when offshore and in distant lands. GM wouldn't allow that override voltage limitation to be changed at a factory dealership. Certainly a good tuner could reset it. Despite using a battery tender, every month or two I put a digital charger on my ZR1 and let it fully charge the battery to 14.6 volts (assumes 77 degrees ambient battery temperature). Could add years to the life of your battery if you keep a tender on it as well.

Only found that restriction on my ZR1, not on any of my other Corvettes. Never could confirm a reason for that driving voltage reduction compared to the Z06.
Just my 2 cents.

Anyone know if you can change the settings in HPtuners? Be nice to get full power out of my fancy fancy aftermarket alternator.

Thanks everyone for confirming. You never know on a used car with previous owners what has been added or not.
