Sh**** the connector I have on this car has 19 pins I don't get it....................

you need to get both wiring diagrams and match them up appropriately. unfortunately, they aren't all 100% match up and the wire colors vary greatly on both sides of the connector.

yea sorry I can't be much more help. I've done 1 eta to m50 harness adapter and I had to go through about 5 different wiring diagrams before I found one that was close enough. Even then, some things still weren't there and I had to guess at a few.
