2G What’s this connector for??

[Mamuthemechanic]

Quick summary. Installed a OHM Racing tucked harness in my 2g. Everything is fine and car runs as it should, but I have one connector behind radio that is not connected to anything.

Oh and I did pull the old harness out before the new one, just don’t know what this is used for? Any help would be appreciated

RIGHT SIDE OF BIGGER BLUE CONNECTOR THE SMALLER BLUE ONE?

P.S This is not my harness in pictures using it as a reference

RIGHT Side smaller blue connector!

If I remember correctly, the blue connectors connect the engine harness to the chassis harness.

Yes i understand that, thanks , the bigger of the two I have plugged in, it’s the smaller one on the right , I’m trying to figure out its use and what it’s for I don’t have the female side anymore to connect

It’s cruise control related and more utilized in vehicles with automatic transmissions. If the OHM harness is a race harness, it makes sense to have deleted this connector.
