Aftermarket Head Unit issue.

Guys, hope all is well. My stock head unit recently went out and I’m finally getting around to replacing it with an aftermarket one. I didn’t go expensive and crazy. I just ordered a Boss 9700a to get me by. I ordered a harness off of Extreme Terrain & most things hooked up except for one male connector from the truck. I will post a picture below of the connector is was. If anybody knows what that is, I’m thinking more speaker wires but I’m not sure. What harness did you guys use when y’all switched to aftermarket? I’m in need of advice. Thanks in advance guys. Be safe.

 

I used the Maestro harness. PAC makes one too.

 

Do you have a part number of the one you used?

 

if it's a 24 pin connector it is most likely your factory back up camera plug

 

It is a 24 pin.
