i got a bosch universal o2 sensor for my hatch..i have a b16 swap and it has the 4 wire o2.....the bosch one has 2 black wires 1 grey and 1 white...i think the stock harness has a green.....does any one know know which ones to hook up? thanx

 

anyone???

 

anyone off werk??!?!

 

Pretty obvious that the grey goes to the green, dont you think?
Next time, search beforehand...this information is easily found

 

we need to know which harness you have, which ECU you have and what year/model the car is to give you the right colors to match up.

generally speaking...
2 black wires - heater
1 grey and 1 white - O2 signal

 

well do you just strip the wires and connect them? or do i have to use the stupid looking harness thing it came with?

 

A smart person would cut the connector, w/ a few inches, of wire off the old sensor and connect the pos bosch unit to that. This way it will connect to the factory harness on the car.

 

stock 1993 civic si harness......im running the stock p28 or the gsr p72....seems to pull harder with the p28..im gettin it chipped soon.....1993 si hatch with b16

 

so just strip the wires connect them then cover it up with electric tape or get some fancy connectors?

 

use solder and, yes, tape too

 

do i have to solder or can i just use a smush connector thing......i am not good with wires and ****.....

 

go ahead and use butt connectors
it doesnt matter because the sensor will foul out quickly anyway

 

why will it foul out quickly......i can have my friend solder it if it isnt going to foul out...i was just trying to take the quick route.....
