I am trying to identify parts inside the engine bay of my truck. I have taken some photos of the parts that I was hoping that someone in the forum could help me identify what they are and what they do. As you can see, these are all located near the solenoid. I think that the "Black Circle" is my MAP sensor, but the "Red circle" is a red connector that seemingly does nothing or is not connected. The green circle and arrow is to a part that was at one time connected to the frame- I think near the solenoid- with a plastic pin. It is now laying on the plastic wheel well now. This piece is a wire that has some sort of clipped in piece. Obviously, I have no idea what it does in the grand scheme of things.
Any help identifying what these parts are and what they do is very much appreciated.
Black circle part: MAP sensor? Red circle part: ? Green Circle Part: ?
The red is the EEC-IV Diagnostic port - where you connect & talk with the truck's computer and pull codes from.
Nearby - above it in your pictures - is a single wire with a gray connector, this is also used to talk to the computer.
The green, hard to say... kinda looks like it could be the SPOUT connector - SPark OUTput - it is a wire used by the computer to monitor & control the ignition module. One removes that connector when setting the base ignition timing (doing so removes control from the computer) and then reconnects it after the base timing is set; the computer handles timing advance/retard from thereon.
Thanks for your help with this! Now I can start to follow the threads and know what guys are talking about.
I have a huge learning curve but this site is great and all you guys sharing knowledge and information is invaluable.
