Are you sure you are on the correct connector number?

In C0287, I see that pin 20 connects to pin 18, providing a link from BCU 661-pin 8 to C0675 pin 1, which goes to the XYZ switch. Both wires are green/brown. It is a two wire header (section of the plug).

The way I found this, and it may work for you, is to go to the circuits manual, and use the seach feature for C0287. It shows up 77 times in the circuits. You can also searh for the combination PB, it shows up 30 times.

I would go by circuit diagram rather than pin out of connector on connector page, if no match. The RAVE does have typos and other things, sometimes they have lists at the start of the error pages. But since it is no longer supported, erors won't be fixed.

 

Yes, I have read all of the manuals extensively. I am positive it is the right connector, right location and they are even color coded. The question is, if the wires are not in the right pin location how do I verify how to connect them. The pin out is the same regardless of which manual you look at. My point was, even my others were wrong but by reading the manuals it was easy to see that wires of the same color were common, thus, join them by color. Not the case on this connector and that is my problem. They are not all joined just by color AND mine does not match up.

 

Well, I would go back to using the schematic as the base, usually those are checked by more pairs of eyeballs. And when at Home Depot or Lowes, you might look in the low voltage wire department for a tone tracer. You connect it to a wire at a known point, it puts a beeping tone on it, and you touch the wire with a plastic wand pickup to hear the tone and trace the wire. Used by phone companies all over, you don't have to srtip the wire to test. see Tenma Inductive Tone and Probe Cable Locator Kit | 72-8500 (728500) | Tenma
