Critters ate through some wires. I have fixed all except the purple and yellow ones from the air charge sensor. I don't see where they go into the harness or wherever. I see no broken wires to connect them to.

Do you mean the air temperature sensor that is on the intake duct? The yellow is a ground, the violet is the signal back to the ECU. The wiring should go to a nearby harness.
Or do you mean the Charge air pressure sensor? It has a 4-wire harness not a 2 wire though.
These should point you at the right area though.

Thank you. Yes. The one on the intake duct. I can find a ground easily enough but the violet wire to a harness may be another story. Any idea which harness and which pin?

From the diagram it looks like I need to locate PCN 151-2 and the slot c175b.

The violet with gray wire goes from the sensor to terminal 75 in Connector 175B You also want the sensor to be connected to the same ground reference as the other sensors, not to engine or chassis ground. It looks like you should find the original wiring if you go to the fender and look for a single piece of harness hanging in the wind, as it has its own pigtail. You don't want to leave that disconnected as it could ground out and cause major problems. It's probably just laying there along the area below the intake duct.

You're welcome. We'll be here if you need other assistance. OH and for repairing those wires a good crimp and seal will do the job. Honda sells a tape with capsaicin in it to help with the critters, but I've seen it chewed through.
