need fuel rail help
I had to pull the head off my truck. I have an 88 300I6. There is a plug coming off of the fuel rail, I dont know where that plugs into. it has 2 black wires. its towards the fornt of the rail. I have the air charge sensor and the coolant temperature sensor both hooked in right. Any help is greatly appreciated.

I'll try to get a picture. At the front of the engine, where the fuel rail bends and turns back, is a little almost like a resistor with two black wires running rom it to this plug. I'm at work and wont be home till tomorrow, I'll try to get a picture then.

That's the cooling fan temperature switch. The blower/fan is mounted on the middle of the passenger side plastic wheel well.
Its purpose is to blow air thru a tube to cool the fuel at the fuel injectors.
The only time I see the blower on is when you shut the engine off on a hot day. It runs for a minute or so and then shuts off.
