to make a long story short im doing a b16 swap. i got all the wires from the sensors threw the fire wall and ready to go to the ecu. the harness already has pins in the slots. do i just splice into those wires or do i take the pins out and put the sensor wire connected to a new pin in there? tried searching but couldn't find my answer.

*edit* forgot to mention its a 90 si hatch

Read about o2 sensor wiring otherwise you will hook it up backwards:

i used that sheet from katman to do all the other wires. the blue and black wire on the pressure switch goes to b5 but were does the black wire connect to

 

Put a ring terminal on it and ground it to the thermostat housing...

 

are you certain it's a ground?

 

Yes..I looked at my car just to make sure..
It needs power and ground to complete the circuit..

 

cool i did a quick search as found that it is a ground. thanks again man
