Asked this over in the PCM section but nothing certain
has come out yet. I want to try and fix the lazy O2s on
this blower, stainless-headers '04 Silverado SS I've been
working with. If the 'vette rears plug in that'd be great,
anyone here know if the front O2s connectors are the
2x2 square style? If not, I could use a connector pin
assignment figure so I can swap connector bodies from
the old to the new 'vette high-wattage sensors. The
truck is about 40 miles away so I can't just crawl under
and check for myself (never mind the pinout question).

 

They will work but not without taking plug off stock 02 and putting on the vette 02. I put the vette 02's in the rear on my truck and thats what I had to do. Stock 02's are same front to rear.

 

Call caspers electronics. They will probally know. If they arn't the same connector they can make you an adapter.
