Hello Hal,

Yes, we do have the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C44FR as a confirmed fit for your 2025 Chevy Equinox. Are you still having issues with it not working?

I see that we do have a pre-order # C88RV, if the 56427 is not working then you most likely need the one with the relays they are currently designing.

If you placed the order with us on the 56427 please let me know the order number so I can get a return label sent to you.

Curt 56427 has been installed by Brantley Trailer in my 2025 Equinox. My question: is Curt 56427 electrically and physically the same as Curt C88RV?

@HalT Yes Hal, the Curt part number for the # C88RV is 56427, we have to change the part number for our site because we carry for so many different manufacturers.

Wondering how they got this to work. I bought a wiring harness from AC Delco and it does not work.

@AustinN The wiring has been a little finicky on the 2025 Chevy Equinox, so you are definitely not the only one who has run into this. The harness we have actually been able to get working properly is the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C88RV. I would recommend going with the Curt harness rather than trying to make the ACDelco harness work.

@KateF I’m sure it may depend on but do you think Curt will work in it’s natural state after the dealership updated the light control module or do you think we will have adjust the wires like some are saying. I’m taking my car to the dealership on Wednesday and want to prepare them for any situation. I took my car to another dealership and they simply couldn’t figure it out or didn’t make the effort to call GM for assistance.

@AustinN After taking a closer look at the # C88RV, I see that the product is no longer active, which tells me there were issues with that one as well. I really wish Chevy hadn't made the wiring on the 2025 Equinox so sensitive because the aftermarket manufacturers have definitely had a hard time getting this figured out. At this point, the only option we have is the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C44FR, and that will only work if your Equinox has the factory tow package. It looks like you may end up having to pay an arm and a leg through Chevy to get the correct wiring for your Equinox. I am very sorry about that, and hopefully the dealership you're going to Wednesday has better luck getting you some answers. If you remember, please let me know what they find out, we are eager to know!
