looks like something a PO did. i don't recognize those connectors as stock... are they in the dash or?
The wires have red overspray all over them...so it is really hard to tell. In this picture...looks like radio wires. The actually factory red single plug looks like the radio illumination lamp wire.
The red plug has two white/blue wires to one side (the two twisted on the right) and two light blue wires on the other. one of the blues is a pigtail (about 5in. long)with single factory red plug
Look like radio wires to me. As I said earlier....the wire on the far left is the radio light. The one on the far right...look and see if it goes up to the dash speaker.
No dash speaker and the one on the left has pulsating negative power. But I will trace down the right side and see thank you
Got to check it, yes the left is lights, the center is switched power/lights and the right plug is lights/ground.
If the looped wire is the one I'm thinking of the car will not start without it so I'm thinking it has to do with neutral safety.
