i just bought a used UTEC and in the package was the following cable, not sure what it is. any help would be appreciated. please no flamming, as stated i am completely clueless

 

It's the MAP sensor to measure pressure inside the intake manifold. You can unplug the spare port cap on the upper plenum. Plug a hose into the black map sensor and the other end into the plenum. The four prong plastic connector plugs into the UTEC.

 

thanks for the prompt response. i am running a NA setup, is this mainly used for FI? or would it be beneficial for me to install?

 

You don't need it for NA.

 

looks like i have a map sensor for sale then
