Catalytic Converter DIY?

Any good catalytic converter DIY threads out there? Need to replace and got a good deal on two OEM rebuilt units from Pelican. Been soaking O2 sensors in PB Blaster for a few days and ready to get started. However, can't seem to find connectors for rear O2 sensors. Any pictures out there? Is this one I should just leave for the pros? Searched and did not find anything so thought I would ask before giving in. Thanks in advance, Thom.

Are you getting code P0430? I ask because that code pops up now and then and I've read its bad cats(s). Of course it could be alot of other things like MAP sensor or a small leak someplace.

I'm getting P0420, Catalyst System Efficiency Below Threshold (Bank 1) . So, I'll do them both. Dealer, whom I trust, also told me they needed to be replaced.

The rear o2 sensor connections are under the engine cover on the intake side. Let me know how it goes, i badly stripped my rear o2 sensors and I'm considering removing the entire header to replace.
