IVR Installation on 65 Dart Cluster

I'm electrical-ignorant so I really hoping someone can show me where to connect the IVR 3 on my circuit board. As I understand it, I'll need to first remove the face of the fuel gauge and disable the points inside. I have the cluster out and ready to install the IVR. If anyone can use these pictures to illustrate, I'd be very, very grateful.
