I have a 1990 F250 351W. I am wondering what the 3 main relays in engine bay are.
Brown plug base........ EEC Relay
Green plug base........fuel pump relay
Grey plug base..................................... that is the one i can't figure out as the part numbers on it are worn off and i can't read it or find this info after much searching
part numbers would be very helpful too. Thanks in advance.
thank you much. i realized it was the tow relay when i flipped the mounting frame over and looked at it. my brother had modified and tucked a lot of stuff in the engine bay so it wasn't in factory orientation. appreciate the response.
