glow plug relay

[dgreene612]

Can any one tell me if the two small wires on the gpr matter which side or terminal they are on ? What will happen if they are reversed ? I am working on a 95 powerstroke

If a glow plug relay is like any other contactor than the two small wires energize the coil and it would make no difference. Thats just an electrician talking not an auto mechanic.

Makes no difference which terminal as long as u put on on each small terminal.
