Hi everyone,

I am using the Scosche NN04b harness to wire up an Alpine 940bt and an ASWC. Looking at the Scosche harness the pins do not match up with what the factory harness states. The NN04b has pin 16 as (a red wire) 12v switch when the factory harness says pin 7 is the +12v switch and pin 16 is for the radio, which I will use for the ASWC. Will it hurt anything if I move the red wire on the NN04b from pin 16 to pin 7? Also is it ok to add wires to pins 8 and 9 so the dimmer will work?

NVM I had a slow moment. I did not realize I had the NN04B upside down when counting the pins. pin 19 should be on my right.

Wiring harness confusion!!
