I've searched the archives but can not find a definitive answer to this question.

I’m in the process of installing the power window wiring in my ’67. In the AIM, A31, sheet A1, the wire runs along the right side of the tunnel and up the firewall where it attaches per clip #3, p/n 3771973 before it does a 180 degree bend, and back down to the cross brace where is splits left to right. Does anyone have a photo of this installation or can you tell me what kind of clip this should be, or what it attaches to at the firewall?

Thanks
