Looking for the fuse box in your Kenworth T370 but not sure where to start? Finding it quickly can save you precious time during electrical troubleshooting or when replacing a blown fuse. The good news is that it’s placed in an accessible location—once you know where to look.
Where Is the Kenworth T370 Fuse Box Located?
The fuse box in the Kenworth T370 is located behind the dashboard on the driver’s side, specifically behind the left-center dash panel. This standard location is consistent with other Kenworth medium-duty trucks in the same family, including the T170 and T270 models.
How to Access the Kenworth T370 Fuse Box
Getting to your T370’s fuse box is straightforward but requires removing a dash panel. Here’s a step-by-step approach:
- Locate the dash panel screws – You’ll find two screws holding the dash panel in place:
- One on the left side of the panel
- One on the right side of the panel
- Remove the screws – Using a Phillips screwdriver, carefully unscrew both screws.
- Remove the dash panel – Once the screws are out, lift the panel upward gently and then pull it outward. Take your time with this step to avoid scratching your dashboard.
- Access the fuse box – After removing the panel, you’ll see the fuse box mounted directly behind it.
The entire process takes about 3-5 minutes, even for someone doing it for the first time.
What to Expect When You Find the Fuse Box
When you’ve successfully removed the dash panel, you’ll discover:
- A fuse panel with a protective cover
- A diagram on the cover showing the layout and function of each fuse
- Color-coded fuse arrangement for easier identification
- Spare circuits labeled with red (battery) and orange (ignition) markings
Understanding the Kenworth T370 Fuse Box Layout
The fuse box layout in the T370 is organized systematically, but it’s worth noting that positions may vary slightly between model years. Here’s what you need to know:
| Fuse Area | Typical Functions | Color Coding |
|---|---|---|
| Upper Section | Lighting, wipers, HVAC | Various |
| Middle Section | Engine, transmission, ABS | Various |
| Lower Section | Accessories, radio, cigarette lighter | Various |
| Spares | Backup fuses for replacement | Red (battery), Orange (ignition) |
Kenworth designs their fuse boxes with accessibility and organization in mind, making maintenance relatively straightforward once you’re familiar with the layout.
Common Issues with Kenworth T370 Fuse Access
While accessing the fuse box isn’t difficult, there are a few challenges truck owners sometimes face:
- Tight space – The area behind the dash can be cramped, making it difficult to see all fuses clearly
- Worn screws – Older T370s might have worn dashboard screws that are harder to remove
- Fuse identification – The small print on the fuse diagram can be difficult to read in low light
A handy tip is to use your phone’s flashlight to illuminate the area and take a clear photo of the fuse diagram for future reference.
Tools Needed to Access the Kenworth T370 Fuse Box
You’ll need minimal tools to access your fuse box:
- Phillips head screwdriver
- Flashlight or work light
- Clean cloth (to place the screws safely)
- Fuse puller (optional but helpful)
Having these simple tools ready before you start will make the process much smoother.
Model Year Variations in Fuse Box Location
While the general location remains consistent across model years, there are some slight variations worth noting:
- 2009-2013 models: Fuse box is directly behind the left dash panel
- 2014-2017 models: Similar location but with an updated fuse panel layout
- 2018 and newer models: Improved access design but same general location
The Kenworth T370 body builder manual provides specific details for different model years if you need further clarification.
Fuse Box Maintenance Tips for Kenworth T370 Owners
To keep your electrical system running smoothly:
- Check connections regularly – Look for signs of corrosion or loose connections

Regular inspection of your fuse box can prevent electrical failures on the road.
Adding Auxiliary Equipment to Your Kenworth T370
If you’re looking to add accessories or auxiliary equipment to your T370, Kenworth has made provisions for this:
- The body builder manual recommends installing a 15-ampere fuse in location F36 for auxiliary equipment
- Spare circuits are available behind the dash specifically for additional equipment installation

Troubleshooting Electrical Issues in Your Kenworth T370
When electrical problems arise, the fuse box is often your first stop for diagnosis:
- Identify the affected system – Determine which electrical component isn’t working
- Check the fuse diagram – Find the corresponding fuse on the cover diagram

- Replace if needed – Always replace with a fuse of the same amperage rating
Remember that repeatedly blown fuses indicate a deeper electrical issue that needs professional attention.
