...what do you do with the wiring harness end of the plugs? I’ve got O2 sims in there now and I don’t really want to remove them (I’m lazy), plus having something plugged in keeps the connectors clean.
Is there a problem with leaving O2 sims plugged in after having the rear O2s removed from your PCM? Does it confuse the PCM that it’s still getting a reading?

You can leave 'em plugged in if you want to. Doesn't matter. Or you could remove and sell them which is what I'd do. <img src="gr_stretch.gif" border="0">
