No go.
My old lights have two plugs in the back. One with 4 spaces for wires and another for 6. The 4 wire plug has only 3 wires. The 6 has 6 wires. In addition to the aforementioned wires, there is a brown "extra" wire.
865sp300e was kind enough to forward something, but SLs must be different.
Any help?

Thanks
