U-02 check connector fuel pump circuit
I'm using the PDF version of the wiring diagram. In tracing the fuel pump circuitry there is a so called U-02 check connector and apparently it's located in the fuse and relay box, but what's the purpose? I've searched but have yet to get relevant info. If in the fuse box then it's there to be readily accessible. It's seems to be in parallel with the PCM circuit if I read it correctly.

Right. Thanks. So basically it bypasses the PCM on the relay side (low pressure). Also on the diagram I assume that F refers front harness vs R for rear harness. L/B and L/R should also be the color code but I don't think I've seen a legend for the codes.

Thanks. No doubt R=red, B=black, W=white, but was this actually on a specific page somewhere and is a copy available somewhere to make the list is complete?
