CPS crank postion sensor wiring help

Hi, all I have a 95 camaro z28,and the crank sensor plug wire got snatched by my belt. Can't seem to find the broke wires on the harness. Can anyone help me locate these wires so i can tie in a new plug..My info i have says the 95 does not have a crank sensor,only the 96-97 do . any help would be welcomed thanks..

Yeah, 95s don't have a crank sensor, so what are you looking at?

Thanks for the reply shoebox, What am i looking at is a good question..its not my ride ,but the title says its a 95. there is a crank sensor on it,so that leads me to believe its a 96 motor. I see the sensor plug at the bottom of the crank ,but can't find the plug or wires that went to it.. I have a plug that a friend found at a local junk yard,but can't find the wires to tie into.. Guess what i need is a wiring diagram that will show the plug , an wiring route, so i can find were the wires were pulled out... so far i have looked an looked ,an can't find the broken ends of the 3 wire plug..

If its a 95 model year chassis, there is no CKP wiring in the harness. They didn't put the CKP wiring in the 95 harness, because the 95 didn't have the CKP. When they put the 96 engine in the 95 chassis, they would have just left the sensor in the timing cover, to fill the hole, and there would have been no wires for them to connect it to..... that's why you can't find a place to plug it. If the problem is you don't know what year the chassis is.... why not find out and come back and ask the question?

EXACT SAME? Did you read post #4?

1- Is your car a 1995 model year?

2 - Is there a crankshaft position sensor inserted into the timing cover in the 7:00 o'clock position?

3 - And you once’s had a wiring harness with a connector attached to the crank sensor?

4 - And you somehow “lost” the harness, and are trying to find out where it is so you can plug it into the sensor in the timing cover?

Is your engine running?

5 - Does your car have a 1995 PCM? If so, it does not need a crank position sensor signal to run the engine. So you don't need a harness to connect to the sensor. The crank position sensor was added in 1996 to meet the OBD-2 requirements for misfire detection. It serves no other purpose. There is no misfire detection function in the 1995 OBD-1 PCM.

Answering questions 1 through 4 will tell us if you have the EXACT SAME problem.

If, like the thread starter, you may not be sure of the year of the car, etc, provide the correct info.
