Where do the solenoid go on the firewall solenoid on a 2001 ford f150 5.4l?
After bolting the relay to the firewall (that grounds it) connect the side closest to the battery, to the battery. The other big bolt stud on the other side goes down to the starter solenoid. The two smaller terminals should be labeled with a letter. Surf the net, they will tell which one goes to the ignition switch
My 2001 super crew only has two big post and one small post . The small wire has a rubber boot that u just push on. I am not for sure if it goes to ignition switch or to solenoid located on starter. Ford said the wire was breaking down at starter and had a replacement wire that is suppose to help bendix engage flywheel. Let u know if it works .
