i looked in the back of the block and theres is a hole but theres nothin there and on the side theres a snesor connected to the 02 and the map sensor so does anoyne know where it is on a 1997 integra gsr, cuz my check light is on

 

under the intake manifold at the top of the block in the center.
Will be very hard to see on a gsr

 

theres nothing plugged to that so how can i hook it up cuz i dont see any open wires maybe the guy who installed ym turbo took it off on purpose?

 

that would be very odd if he did
