Ok. I went out and nothing is labeled. How do i tell which is which? I have on the right harness into the box a Red, White, Blue, Gray, and Yellow wire. The rest including the other harness are all black. Which ones are which?

They are labeled on the black connectors that goes into the ecu. You just have to look REAL close. The red, white, blue, gray, and yellow, and black are probably the WBO2 wires. They are located in Blue-F1; Gray-F2; White-F3; Yellow-G1; Red- G2; Black-G3
