People with LT help me out

i was unaware of the fact we already have heated O2's...previously all of my vehicles had generic O2's...

do the LT's have proper emissions hookups even though they're not exactly emissions legal? my mechanic doesn't care as long as it looks like it's working...meaning i need cats and all my crap hooked up...but if he sees nothing connected, i don't get my sticker...basically as far as he's concerned as long as it doesn't throw any codes and passes a sniffer, it's gtg
