FD Decat Fitting

[GhostWKD]

Hi Guys,
 
Fitted a decat yesterday, understand that the breather type connection is the air pump and can just be left unplugged (my air pump is disconnected anyway)
 
Stuck with the heat sensor though - have read somewhere that i need to join two wires together to cancel it out? but cant see any plug for this sensor to remove it or any wires to join etc?

Cheers,
Alex
