almos done re-doing te whl wirin harness for my 6.0 swap intmy ecamino, but i seem to have ran into a pretty big ad cnfusing issue...my O2 sensor wirs donot match my wiring diagram i got from mitchell. issue is

mitchell diagram
tan- sensor lo
purple-sensor hi
black- gnd
pink- power

my harness
tan- sensor lo
purple-sensor hi
green- computer red-80
green/white- computer red-74

everything matches but there are 2 greens ather tan the black and pink... was thinking i would just re-wire it the same way, but proble is that im using a compuer off of a different truck then he one the engine and harness came from. has anybody else ran into this issue? my postcat sensors match the diagram perfectly but whas up with the pre cat wires?

truck motor and hrness is from a 2000 2500 truck, i figure following the diagram might be best bet?

You need to use the schematic that matches the pcm you're using, no matter what it's off of or what the harness is off of or the motor is out of. The wiring has to match the pcm.
