I have a 95 S-10 and it has the 7 wire trailer harness. I have the 7 blade RV socket all wired up in back to the harness and working. My problem is, I can't seem to locate the blue trailer brake wire under the dash. Can someone lead me to it?

Never mind, I found it in the engine compartment by the firewall on the driver side. It was just the blue wire with no end or terminal on it. It was dirty , so it was hard to see.
