I'm waiting for Brain to get back to me on what was the standard setup for this harness, but I thought I told him I had an LC1 and that I was going to hook it into the MS, but it seems none of the wires are loose.

Again, this might seem like a stupid question since there is that wire there that says O2 on it in the middle. I'm thinking I need to use the middle connector and hook the wideband up to the appropriate wire, but I wasn't sure about the labeling so I wanted to double check.
