I just bought a 3rd brake light and i am having trouble wiring it. I cant seem to find were it plugs in at.
This is the wire from the led taillight

And this is what comes from the pickup.

There three plugins that look like this coming outa the pickup fro each of the bulds. The new light has only one cord and i dont know where it plugs in at.

This thread should help.

The connector is back in there a bit. You need a pair of long needle nosed pliers to pop the connector out of the hole it's in.

 

Thank you i got her now.
