Welcome to the OB.
I would suggest that you purchase at any auto parts store this manual, very informative. Haynes Techbook Diesel Engine Repair Manual. about $16
There is some misinformation in the previous posts.
If your glow plugs are the spade type where the wire hooks on then they are not ZD9, they are ZD1 for Motorcraft/Beru, a ZD9 glow plug has a bullet style connection.
The starter relay mounted on the pass fender has nothing to do with the glow plug controller, the battery POS. wires are direct from the battery, they are fusible links, size 12AWG, there is a connector that sometimes will melt due to corroded contacts.
I would suggest you get a timer for the block heater, the heater is 1000 watts, only needs 1-1/2 hrs plugged in to heat the engine.
One other thing not mentioned is the coolant, it's important that the SCA (Suplemental Coolant Additive) be kept up, Not knowing what you have , it would be a good idea to change it, a good coolant is FleetGard with the SCA in it, good for 100,000 miles, 4 Gal's of concentrate and 4 Gal's of steam distilled water. Available from NAPA or IH truck dealer.
