Id these plugs

[The Shadow...]

Hello, can any help I'd these plugs? I believe the last 2 plugs ( one doesn't have the plug just wires) are the 02 plugs.
The car is an 89 vert with a c4 tranny and a b and m shifter. I have had this car for to long and this is my first ford/ fox.
I know the vss plug isn't there. Not sure what area it come from so I can look for it.
Car runs pretty well. It does have the occasional shut off when slowing down. (I believe the vss would fix that).

Top two are the harness that the NGS snd VSS would normally connect to. However they are FUBAR.

What is the ngs?

Nuetral gear switch. Tells the ECU the manual trans is in nuetral. It’s not present on AOD cars.

was the car originally a 5-spd or AOD? I can’t actually see the wire colors to confirm if it’s there.

but that harness is this one

Mustang Manual Transmission Harness (87-93) 5.0 - LMR

Use this 5.0 Resto 1987-1993 Mustang 5.0L manual transmission harness to repair your damaged or melted harness.

There are three connectors on it. One is the VSS (2-wire) one is the Nuetral Safety/reverse light harness (4-wireplug) and the msnual cars would have a 2-wire plug for the NGS.

Btw, bottom two pics look like the o2 harness. Not 100% sure however

I'm also trying to figure out why my back up lights don't work, lol

I ordered a replacement harness for the vss, ngs. Also a new o2 harness and 02 bungs. The car has full length BBK headers and the ports are plugged and there is no clearance.

Replacing that harness would solve a few issues for you

I wanted the vss plug to work so the shut off after stopping sometimes would quit( usually after moving from at low speed.
Also I got a raptor 2 stage shift light, and it uses input from the vss for the one stage.
