Thanks for your help Indy! and yes definitely going to get a few other opinions/quotes. And "littlebeast" is right lol.. it took me several hours just to remove my 2 downstreams with correct tools and torch but I could not even see where the passenger upstream plug/harness go's/is. let alone unplugging it? The driver side seemed like I could probably do it with a bunch of cursing and ingenuity. Hey LB Just wondering how you did your 2 front/upstreams so quick? I was wondering if we could go through the console under the shifters somehow to get to those plugs?
