Engine Compartment - Wiring Items Identification.
I didn't take this car apart but I have to put it back together. There are a few things I need ID'd under the hood. I'd like to eliminate as much as possible. Working on getting the DME harness out. The car's gonna be running non DME with carbs. 1988 model.
I'll start with these three:

Perfect, number 3 is tied in to the main harness.
Not sure if the fuel return is going to be necessary. And the brake vacuum line is located right where it's counterpart is coming off the carb.  How about this one, mounted just inside the left upper shock mount.

The DME harness has been completely removed. I understand I've lost my source of power to my fuel pump and to my coils. I'll have to figure something out there.
Can anyone identify the two parts at the end of the harness marked 1 & 2? These were plugged in under the fuel filler near the front fuse box.     Also, does anyone recognize what this is? It's possibly something aftermarket. When I opened it a tube type fuse came out and fell behind the gas tank.

Yellow is DME relay signal wire for start, black/purple and one black is tach, other black is alarm wire.
Is that a green/yellow wire? To A/C from DME.
