Default 99 SC300 radio wiring diagram?

Its not the same plug set up as all the SC300 diagrams I'm finding.

I have one 16 pin plug "white"

and one 6 pin plug "blue"

Does anybody have the wiring pin outs?

Id like too get as much working as I can...amps..sub

Ok guys, I found this.

Does anybody know what "back up 1 & 2" are on the big plug? Are they 12volt constants?

How bout "Ant 1 & 0" on the small plug?

Then theres the "Sub Antenna"?

All the wire colors are different and the plugs dont match. From what Im collecting, the 99-00 SC's are using the same plug and harness as the same year GS400's. Ive tried searching using that criteria and still come up with nothing.

Thanks for tryin bro
