I am finally finishing my engine putting it in and now have no idea where any of the vaccum lines go again as i said in many threads i did not take the engine out of this car nore did i tear it down =( but i just found out today that i need a heater water suply and return tube if anyone has any pics of that it would be an awewsoem help beacause im guessing there is a connector on that i have my coolent temp sensor in the hole closest to the thermostat but there is another conector on the side of that that i have a pic of. also a wierd looking connector where i thought the passenger side o2 sensor should be but isnt also a pic of that. all of the vacum lines are torn up and broken i have a vac line map but cant make any sence of it and have been on a website i found in soem other threads if anyone has a picture or two it would be a major help! like pcv, egr, all man outlets... and so on. also is there suposed to be only one wire going to the starter and it grounds itself out through the case or did i screw that up thanks if anyone needs more pics to help or better pics or any more info just tell me ha ill help you help me i just wanna drive it ! thansk alot :bang:

The missing heater supply tube has the water connctions for the two water cooler line in the top picture.

The second picture is the EGR valve. It connects to the EVR (Electronic Vacuum Regulator) on the back side of the passenger side strut tower. The EVR then connects to manifold vacuum.

The missing item in the picture of the ECT sensor is the Carbon Canister solenoid. It controls the vent to the fuel tank.

As a side note, if you can find a junkyard with a 'stang or know someone with one, being able to look under the hood yourself would probably be really helpfull. These cars have quite a few different sensors, wires, and vacuum hoses, though not nearly as bad as some 80's japanese stuff.

I also noticed in your first picture, you are missing the TPS (throttle position sensor) which mounts to the top of the throttle body, and has an electrical connector on it. You may well already know that, just thought I'd point it out.

Good luck, it will all be worth it when you're done.
