No problem. That what the forum is all about.

Yes, pins 7, 9, & 15 on the big connector.

No, do not disconnect them from the connector or you HU will not work. You need to "T-in" to these three lines- meaning leave them connnected to the big connctor but also make a connection to these three wires with the corresponding wire from the 3pin connector.

And the adhesive on duct tape is conductive ... real electrical tape or even cloth hockey is preferred
