I will be installing this on my '85, so it should be the same as your car. Reading through the posts, it sounds like wires at the column switch will be spliced and ran to the relay. Here is the Bertone wiring diagram:

So I made this diagram - it shows how the relevant wires are actually connected. I listed the steps to take (based on Rachel's directions). Jumpers are shown at the switch connector - it may not be practical to make all connections directly at the connector - given the heavy wire used. I illustrated it that way to avoid over complicating the diagram
LMK if it helps
