87 Iroc 5.7

I need the electronic control module terminal identification schematics for a 87 iroc Camaro with a 5.7 tuned port injection motor. I am having trouble identifying two wires same color, one goes to the knock sensor the other goes to the cooling sensor on the passenger side head right below the exhaust manifold. When I bought the vehicle they were both disconnected and melted the both have the same single wire pigtail with low voltage from the computer. I have been having cooling fan problems and I have put a aftermarket thermostat switch into the radiator so as not to depend on the computer to turn on my fans. I need to trace the wire from the computer to decide which wire goes to which sensor. please email me if you have a diagram that would help me at [email protected]

While quite a few of us own or have owned 3rd gens (I once had an 89 RS) and you'll probably get an answer here eventually they specialize in 3rd gens...
