I've had very good results with this glow plug relay timer. It doesn't use an input from a temp sender to operate. Wiring diagram is easy to wire up. I use the glow plug output from the relay to operate a ford starter motor relay (firewall mounted type) as this relay can carry a higher amperage thereby keeping it out of the glow plug relay.
