The electrical connector to the PCM has 8 ports. They are labeled with numbers 1 to 10. Port 2 and port 8 are blank (no connection). Which device (wire) is connected to which port? Which port is ground? Could you pls. Explain the wiring in the following way:

HO2S bank1 upstream -> port?
HO2S bank2 downstream -> port?
.
Fuel INJ 3 -> port?

.

Thanks!
Martin

I am not sure I understand what connector you are looking at. The PCM connector has about 104 wires going to it, and I am attaching the detail below for this connector.

Here is a guide that will help with testing these circuits if you need this:

Please see the info attached and if you can get a picture of what connector you are looking at, I am sure that will help us figure out what is needed.

Thanks
