one colored wire goes to ecu where does the other go?

so i checked the pinout for my IAT and o2 sensor...since i have CEL's for both...i'm just gonna change the O2 cause it used to work....no big there...but my IAT will not work..so i'm just gonna wire it strait to my ECU and see what happens..

so i went to this site i found by *searching*...

and i have an LS but just minus the VTEC part....i need a RED and yellow wire going to that one pin on the ECU where does the other one go??? just to a ground somewhere..would i be fine grounding it out to my battery?...i'm assuming its a ground but i wanna be for sure...and for the IAT the top wire is for the positive right???

according to the helms manual for an EK civic, the red/yellow wire detects the IAT sensor signal so i would say the other one is a ground and would ground it in the engine or chassis not the battery
