Default 1972 Rally gauges w/120 speedo

72 Lemans sport conv 350-2

OK,
I want to change from warning light cluster to rally gauges on a 120-seatbelt warning car. I have the 120-gauge cluster and want to keep the seatbelt warning system operational. I've searched the forums and found a few different posts about which wires to switch but are conflicting. It seems a lot of the posts refer to guys switching from 120 warning clusters to 140 rally clusters. Has anybody done the switch and can tell me which wires to switch?
