Disconnected wire/connector help

[obanaga]

Hi,

I looked in the engine bay today, and noticed a wire/connector that is disconnected. I have not noticed before since I purchased last July, and the car came with a modified air intake.

I was wondering if someone may know where this connection should be made at, or if it is not necessary after the intake mod? I looked inside the engine bay and couldn't see any obvious missing connections.

Thanks for your help,
Oliver
