I have 83 ranger 2.8 v6 2wd automatic. Can't seem to find schematic of passenger side engine compartment. Below the starter solenoid is a relay and connector and i cannot find what it is to online. It is a 5 pin and it's between the battery and vacuum ports. I thought it was ecc relay but that's a 4 pin. I thought fuel pump but I have mechanical fuel pump. Any help would be great.
