Do these really help? I have been having issues with my bank 1 sensor not lasting very long. I dunno if it's caused by the header moving it back far and the heating element not being adequate though.

I was looking at the wiring schematics between the truck and vette sensors and they don't look the same:

Truck:
A: Low Signal
B: High Signal
C: HEATER LOW CONTROL
D: Ignition Voltage

Vette Rear:
A:Low Signal
B: High Signal
C: GROUND
D:Ignition Voltage

The vettes require a ground in the C port, and the trucks don't....

Can anyone shed some light on this?

That's what I put in my truck. Apparently they have a better heating element and are less prone to fouling when they are further from the engine in cooler exhaust. All I did was cut the pigtail off my old O2's and splice it onto the new O2's, then they plugged right in

Ok so i guess the "C" wire being different doesn't matter then. I have fouled 2 driver's side sensors so far. Hopefully this will fix it.

The connectors are different, so you can't plug them in out of the box regardless. Once you rewire the old connector onto the new sensor you don't have to worry about it.

03s apparently have a different connector. Mine will plug right in. I'll check the wiring diagram for the older trucks o2's to see if their's match the vette's

Ah ok. If that's the case I'd just swap those two wires and call it good.

well it seems like the truck takes a hot(+) signal on "c", and the vette requires a ground (-) signal on "c". everything else matches up.

how would you swap it?

I just PM'ed ya. Match the letters. That's what I did. (I could of sworn it was numbers, maybe not) Let me see if I can find that match sheet for the connectors.

I am wondering as well, gotta get some 02's to go back to CLSD.

I'm hoping someone who has done this w/ an 03+ will chime in and let us know if it'll work and if they make a difference
