Please help me identify these wires. These wires have been just hanging around unconnected since I bought the truck 7 years ago. Picture 1 - This 2-prong connector comes from behind the distributor near the oil sending unit. Picture 2 - This wire comes down along the valve cover on the drivers side. Picture 3 - This wire comes down along the valve cover on the passenger side. Picture 4 - These 3 wires come from a grommet on the passenger side firewall.
