If you’re looking for a 7.3 idi glow plug controller wiring diagram, then you’ve come to the right place. I’m going to show you how to wire up your glow plug controller so that it works correctly with your truck. This is a simple process that anyone can do, and it will only take a few minutes of your time.
If your 7.3 Liter Powerstroke is idling rough, it could be a sign that your glow plug controller needs to be replaced. This part controls the voltage that goes to the glow plugs, and if it’s not working properly, the engine will run poorly. Luckily, this is an easy fix – all you need is a new glow plug controller and some basic wiring knowledge.
Here’s a step-by-step guide to replacing your old glow plug controller with a new one:
1. Disconnect the negative battery cable from the battery terminal.
2. Remove the plastic cover over the fuse box on the driver’s side of the engine compartment.
Locate the fuse for the glow plugs and remove it.
3. Use a wrench to loosen and remove the two bolts that hold the Glow Plug Controller in place on top of the valve cover near where you removed the fuse. Pull out the old controller and unplug any wires still attached to it.
4. Install the new controller in its place, making sure that all ofthe wires are plugged in correctly (the order doesn’t matter – just as long as they’re all plugged in). Tighten down both bolts holding it in place so that it’s snug but not overly tight – you don’t want to strip them! 5 Reconnect your battery cable and turn on your ignition (but don’t startthe engine).

How Do You Test a 7.3 Idi Glow Plug Relay?
If your 7.3 idi glow plug relay is not working properly, there are a few things you can do to test it and see if it needs to be replaced.
First, check the fuse that powers the glow plug relay. If the fuse is blown, then the relay will not work and will need to be replaced.
Next, check for power at the glow plug relay itself. There should be two wires going to the relay – one should have power all the time, and the other should only have power when the ignition is turned on. If there is no power at either of these terminals, then the relay will need to be replaced.
Finally, check for continuity between the two terminals on the glow plug relay. If there is no continuity, then the relay will need to be replaced.
How Do You Test a 7.3 Glow Plug Control Module?
To test a 7.3 glow plug control module, you will need to first disconnect the battery. Once the battery is disconnected, you will need to locate the glow plug control module. The glow plug control module is usually located near the engine block on the passenger side of the vehicle.
Once you have found the glow plug control module, you will need to remove the two electrical connectors from the back of the module.
Once the electrical connectors are removed, you can use a multimeter to test for continuity between the two terminals on the back of the glow plug control module. If there is continuity between the two terminals, then your glow plug control module is most likely functioning properly.
However, if there is no continuity between the two terminals, then your glow plug control module may be defective and will need to be replaced.
How Does a Glow Plug Controller Work?
A glow plug controller is a device that regulates the amount of current flowing to the glow plugs in an engine. The controller monitors the temperature of the engine and adjusts the flow of current accordingly.
The glow plugs are used to heat up the air in the cylinders so that it is easier to start the engine.
When the engine is cold, the glow plugs are used to heat up the air so that it is easier to start the engine. The controller monitors the temperature of the engine and adjusts
the flow of current accordingly.
Thecontroller has two main parts: a power control unit (PCU) and a sensing unit. The PCU regulates voltage and current based on signals fromthe sensing unit. The sensing unit consists of a thermistor and a resistor.
The thermistor measures temperature and resistance changes with temperature changes.
How Do You Know If Glow Plug Relay is Faulty?
If your car is having trouble starting in cold weather, it might be due to a faulty glow plug relay. Here are a few ways to tell if your glow plug relay is not working properly:
1. The engine takes longer than usual to start.
This is because the glow plugs need time to heat up and ignite the fuel in the cylinders. If the relay is not functioning correctly, it will take longer for the plugs to heat up.
2. The engine produces a lot of smoke when starting.
This is because unburned fuel is entering the combustion chamber and causing the engine to run rich. A faulty glow plug relay can cause this problem by not providing enough power to the plugs.
3. The check engine light is illuminated on the dash.
This can be caused by a number of things, but one possibility is that the Glow Plug Control Module (GPCM) has detected a problem with the relay and has shut it off.

7.3 Idi Glow Plug Controller Replacement
If your truck is equipped with a 7.3L Powerstroke engine, then it has an idi glow plug controller. This controller is responsible for supplying power to the glow plugs, which in turn heat up the air in the cylinders so that the fuel can ignite. Over time, the idi glow plug controller can fail, causing the engine to misfire or not start at all.
Fortunately, replacing the controller is a relatively easy process that you can do yourself.
To begin, locate the idi glow plug controller on the passenger side of the engine bay. It will be mounted on top of the fuel filter housing.
Once you have found it, disconnect the negative battery cable to prevent any electrical shorts.
Next, remove the two bolts that hold the Controller in place using a ratchet and socket. Carefully pull out the old Controller and unplug its connector fromthe wiring harness.
Now take your new replacement Controller and connect its connector tothe wiring harness. Then bolt it back into place using your ratchet and socket.
7.3 Idi Glow Plug Controller Relocation
If your truck is anything like mine, the idler glow plug controller is in a really inconvenient location. It’s right behind the exhaust manifold where it gets extremely hot, making it difficult to change out the plugs. I’ve seen people suggest relocating the controller to a different spot on the engine, and I think that’s a great idea!
Here’s how you can do it:
1. First, disconnect the negative battery terminal to avoid any electrical shorts.
2. Next, remove the idler glow plug controller from its current location.
There are four bolts holding it in place – two at the top and two at the bottom. Remove these bolts and set the controller aside.
3. Now you’ll need to find a new location for the controller.
I mounted mine on one of the studs near the throttle body (see pic). Just make sure you choose a spot that won’t get too hot – remember, this component is sensitive to heat!
4. Once you’ve found a suitable location, bolt the controller in place using the same four bolts you removed earlier.
5. Reconnect the negative battery terminal and start your truck up to test things out. The check engine light should come on for a few seconds as usual when you first start up, then go off once things have warmed up sufficiently. If everything looks good, congratulations – you’ve successfully relocated your idler glow plug controller!
1988 7.3 Idi Glow Plug Relay Clicking
If your 1988 7.3 Idi diesel truck is clicking, it could be the glow plug relay. The glow plug relay is responsible for providing power to the glow plugs, which in turn heat up the air in the cylinders so that the fuel will ignite. If the relay is faulty, it can cause the engine to misfire or not start at all.
Here’s how you can tell if your glow plug relay is clicking:
1. Listen for a clicking sound coming from under the hood when you turn on the ignition. If you hear a click, then chances are good that it’s coming from the glow plug relay.
2. Check to see if the check engine light is illuminated on your dash. If it is, then there’s a chance that one of your cylinder’s Glow Plugs may have failed and need to be replaced soon.
3. Try starting your engine while holding down on the accelerator pedal slightly (this bypasses the need for the Glow Plug Relay).
