I have a 01 mustang , the fuel tank says either empty or full , i disconnected the jumper at the fuel pump and theres a 8 cavity connector but I cant find much information , I was wondering if anyone has a connector end image or schematic.
i found a partial and I think the 3 wires next to each other are going to the level sensor , i ohmed out the 2 next to the pink and red , then the pink and red and other 2 individually and all showed 5k ohms.
Does anyone have this schematic or can help me tell me what I should be looking for ?
I mean theres other problems too , the idle revs up and down , its leaking fuel from somewhere but thats my first concern . trying to get the tank down now.

found out that the level sensor wires are brown and yellow and narrowed the issue down to where the brown wire goes into the rubber on top of the fuel pump brass lid , when i move it i lose continuity.
