Default Wiring color code for bank 1 sensor 1 upstream o2 sensor?

I have a 2000 jeep grand cherokee 4.0l does anyone have a diagram or know which colored wires do what for the upstream o2 sensor?

Black with blue stripe
Solid black
Orange with green stripe wrapping around
Green with orange (maybe red??) stripe

Any help would be appreciated. Been swapping wires around for days lol

download the FSM from Cruiser54 website

you need the manual to work on them anyway

not a great idea to swap wires as they go to PCM, and a short can be bad news
