A friend of mine built a portable LC1 wideband for his 99 Camaro. I would like to use it on my 2002 GMC.

He needs to know what each pin does on my O2 sensor to make it work. His O2s plugins are backwards compared to mine. (male-female) I believe the wire colors are black, black, blue and white.

If anyone can point me in the right direction I would really appreciate it. I am trying to tune for my new cam. I know there is alot left in it.

 

This is the schematic I used on my Camaro to run it through the stock 02:

A = NBO2 Signal Low = LC-1 green
B = NBO2 Signal High = LC-1 yellow
C = Heater Ground = LC-1 blue
D = Heater Power = LC-1 red

Hopefully someone will chime in and tell ya if it applies to your truck, good luck.

Something like that would be perfect.

 

No one has messed with the oxygen sensors of these trucks?

 

I let my account at alldatadotcom die so I can't get a schematic, but the above, Supajut's camaro being a '98 doesn't have high and low heater references. I am sure somoeone will hook ya up soon with a good reference. Hit up Innovative's website as well.

 

Ok thanks. I will keep looking around. I hope someone has a wiring schematic to show what each wire does. I think we could take it from there.

 

This is the truck side of the harness...
B1S1 Purple/wht= high
Tan/wht =low
Pink = 12v

B1S2 Same as above


B2s1 Tan = Low
Purple =high
Pink= 12v
B2s2 Same as above


Send me some beer

 

Awesome!!! So just to be 100%. Black is ground, correct? What's your favorite lager?

 

Yup black is ground. Sam Adams white ale for now

 

Here you go...................
