When I use the Renntech DME 7.2 Engine code search this is what i get (same thing for both):

P0153 = Ageing of oxygen sensor ahead of TWC, bank 2
P1276 = Ageing of oxygen sensor ahead of TWC, bank 2

TWC = Three Way Catalytic Converter

So your codes are for the o2 sensor before the catalytic converter on the driver side.

I've attached a picture of where it is on my car which is a 99' so the exact placement of your's might be different.

I've also attached a picture of the connector. There are a tabs on each side of it that keep the connector locked, some guys say that you can carefully lift the tabs to slide the connector off, I wasn't able to, i had to break them off with a small flathead screwdriver.

Good Luck,
