Default need turn signal wiring diagram, 3 wires

There are 3 wires to the turn signal lamp:
blue with green stripe
grey
black

Which is positive, which negative?

How do these wires combine to make the lamp function as both a side marker light and a blinking turn signal?

I think I would like to wire my new Halo projector headlight rings so that they are on when the side marker light is on.

Or maybe just so the blink with the turn signal.

Or maybe both, so it works just like the signal/marker lamp.

The center pair of small gauge black & red wires lights up those two LEDs. Fairly bright; wonder what their purpose is supposed to be?

Maybe they can be wired into the circuit that keeps the vanity lights on for a short time after the door is locked? They might keep you from tripping on the bumper if its completely dark.

Anyone know if there's wiring for that in the engine compartment?

Default Headlamp side marker wiring

Hi there,

If I remember correctly from when I wired in my side markers to my '94, the black central wire on the turn signal connector is the constant negative, and the green (driver's side) blue/w green stripe (passenger side) are the turn signal pulse wires. If you want the angel eyes to act like side makers, you'll need to splice the above mentioned wires together to the new harness.

If in doubt, disconnect the wiring clip from the front headlight assembly and use the multi-meter leeds on each combination until you find one you like.

Hope this helps,

Cheers.

Hey guys I'm looking to wire up a few things for my turn signal assembly,
Actually.... Can I splice into the wires for my side markers?
Then they would be controlled by the switch i want to..
And would actually work pretty nicely, doubling as turn signals...
although it makes no sense to run the leds while my headlights are on...
so is there a way to make it so they are ONLY on when JUST my turn sigs and side markers are on?
