Electrical issue/help

[Tony71c10]

So I installed an electrical fan on my 84 swap and used the pink wire to supply the 12v key power to the relay from the bulkhead. Fan turn on and off with the key. The issue im having is if I turn on the lights and flip the turn signal to the right the fan turns on without the key. If I unplug the column connector its back normal. I been trying to figure the wire diagrams but electrical is not my strong area. I also noticed that emergency flasher won't work with the lights on. Thinking it is all related.
