I have pulled the dummy fuse in the main fuse block under the hood but cant find the wire under the hood that I am to connect to the #1 post to make the plug connection hot for my trailer battery. Where is it and or what does it look like? Thank you, MM9

The fuel pump wire you are looking for is in the fuel pump relay socket that powers the fuel pump when the fuel pump relay energizes. Its the gray wire
