I seriously appreciate your help

. I got an email and want to see if it works in replying, got my auto forums mixed up! So from your response I can splice into circuit 28 the black wire going to terminal #1 on the relay located under the driver side dash. Run the wire to the one terminal on button I have, and run a wire from the other terminal to a good ground. Is there any type of wire and size that you recommend? Remember I'm old and basically a novice.

BTW The Haynes Repair Manual says the relay is either a 3 pin grounded or a four pin. Mine relay is 5 pins!
