Help, am installing manual fan switch on 94 coupe and relay connection color code does not exactly match instruction color code. Have small gauge Green and Pink with heavy gauge Blue and Red on one relay and small gauge Blue and Pink with heavy gauge Black and Red on other. Don't want to connect to wrong wire. Thanks in advance for any help on this.

You will need to connect to the small wires. Use a DMM or test light to find if one side is grounded or hot (usually the ECM grounds to activate).
Assuming you find one small wire is hot (at +12Vdc), connect one line from the sw to ground and splice the other into the relay floating input.
