If you can tell me if it goes on the Intake or the Firewall, that would be helpful

Thanks

Likely that "ChristmasTreeAnchor" goes into matching holes in the FireWall; feel around for that.
Make sure cable is not too close to exhaust pipes or moving\vibrating parts.
CableTies also work well for securing these cables & any extra length as needed.
