Ok, here is a few pics. I need help with where a couple of electrical plugs go and the metal line on the firewall.


what hooks to the metal line on the firewall?


what does the grey plug go to?

Also, there is a sensor in the coolant housing on top, what goes to that? There was another single wire plug hanging below the throttle body coming from the harness that hooks into the tps.

what does the large barb on the throttle body hook to? This valve?


Last, a pic of the truck that was free!

 

It should huck up to the right side or the fire wall when you are look at it.

 

The metal line is the fuel return line. Connect to the fuel presure regulator (rear of the injector rail).

10mm tube on the throttle body connects to the open tube next to the upper plenum (has the white knob on it)

What year is the engine? The sensor on top of T-stat hosing looks like the older engine (son's 85 has it, friends 87 does not)

The plug I think is for a A/C component. Most are not connected that I have seen. It looks like it is taped back to the harness?

 

The large barb goes to the power steering pump.

 

I was told the engine was out of a 90 from the guy that had the truck. The plug you are talking about for the ac, is that the one with the single wire down under the throttle body, or is it the one in the photo next to the red and blue one?

Also, does anyone else have the hose going from the throttle body to the valve that the resonator usually hooks up to? This is the way it came out of the donor truck. If anyone does have this setup, where does the resonator setup go? Is it just eliminated?
