Ok so I recently took my car to a mechanic to have the Exhaust manifold replaced because it had a crack in it. When I got it back I noticed it smoking so I turned it off. The smoke was coming from underneath the car and the idle was dropping and raising without pressing the pedal. So I turned the car off and went to get a friend. When I tried to turn it back on the car wouldn't start. I noticed that the Camshaft POS Sensor wires were hanging down. (not like that when I took the car to the mechanic) I called him and he still has yet to get back to me of course. So I contacted many places only to find that the only way to get the wiring harness is to buy the entire engine wiring harness kit ($200 for knock off or $1000 for KIA) Any ideas on how I can put this back together so my car can be diagnosed to the other problem?I have 3 wires that have little metal connectors that slide over the other end but I have no idea what slot they go onto. One is orange the other 2 are black.
