Which is the front of the harness and rear of the harness? Also there is a sensor that appears to clip on the fuel rail but not sure where? I’ll post pics. Right now I have one end of the harness with two plugs at the rear and the end of the harness with 1 plug at the front I have these two connectors at the back of the engine.
I have this connector at the front is this correct?
Does this sensor clip on the fuel rail? And where?
I think I had it backward it appears as the two connectors go to the front and plug into the intake and thermostat neck. Am I correct ? Also still need to know if that sensor clips on the fuel rail? There is a groove on the sensor that look like it sets against the fuel rail and the clip goes over the fuel rail and holds sensor against the rail. I don’t know what sensor this is
oh I didn’t mention this is off a 1987 f150 4.9 I’ve post some better pics of sensor I think it maybe a fuel rail temperature sending unit This is where I think it clips on fuel rail Pic of sensor without clip Could this be a temperature sending monitoring fuel temp?

Reason: Left info out
I figured it out it’s a fuel temp sending unit for the blower to help cool the fuel rail. Searching through other threads it looks like I can unhook because my blower does not work anyways. And ppl on here said a the blower was never needed anyways and discountined a few years later
