I had broken connectors on the front fuel injectors. I spliced in that 18-wire section of a wiring harness gotten from a salvage yard. I am having trouble properly matching 3 black wires, 3 blue wires and 2 orange wires. The engine will not start. I get an OBDII code P0343 from the camshaft sensor. Can you help me determine where the wires should be connected?

Good afternoon,

I attached diagrams for you but there are several wires with the same color but different controls.

Can you post some pictures of the wires you see?

Thank you! The diagram sections you sent show exactly what I needed to see.
I found a black, a blue, and an orange wire connected to the same interior connector, and an orange wire connected to a different interior connector. The remaining two black wires showed continuity, and the remaining two blue wires showed continuity, so I connected those to the camshaft sensor and crankshaft sensor. Now the engine starts without any OBDII fault code!
If I could find a wiring diagram available to purchase, it might be worth $200.00 or so to keep my vehicle running for another 5 years.

---- Second almost related subject ----
Please listen to the sound in the attached video clip, which starts by showing the spliced section of the wiring harness. (I will wrap each crimp connector individually and wrap the entire bundle before I drive away.) There is a noise that I did not notice before I changed the spark plugs, spark plug wires, valve cover gaskets, alternator, AC compressor, serpentine belt, and idler pulley. It seems loudest at idle speed. It sounds almost metallic to me, but it reduces to barely audible when I disconnect the spark plug wire to the center back cylinder. I thought it might be a spark arcing to the engine, but it continues quietly from near the firewall when the spark plug wire is disconnected. My only other guess is air/fire escaping through the threads of the spark plug. Suspecting a cross-threaded spark plug, I removed the back three new spark plugs and reinstalled them with anti-seize grease. They all came out and went back in without any resistance until tightened normally. I even used a torque wrench to make sure I did it right the second time. The noise seems not quite as loud now, but is still worrisome.

Okay, we can deal with one issue at a time per question. Since it was for the wiring, you will need to start a new question and then I will be glad to address that issue for you.

As far as the diagrams for the car, you can get a subscription to ALLDATA/DIY for your car and you can print out all the information you need.
