Looking for some help, my son has a 1988 F150 5.0. Took front fenders off to replace front core support. After putting everything back together and engine will not start. Fuel pumps will not turn on unless we jump the fuel pump relay. Then it will still will not start. Everything seems to be plugged in except for this one connector, but we cannot seem to figure out where it goes, or what it plugs into and has no power to it or ground. Anyone know what this is for. Drivers side front fender area.
