Mileage Blockers for Pickup Trucks: F-150, Ram, Silverado, Sierra, Tacoma and Tundra

Pickups are the hardest category in our catalogue to order correctly, and it is not because the trucks are complicated. It is because every manufacturer splits its range on a different thing. Ram splits on the CAN-Bus type and the cluster connector. Ford splits the F-150 on model year and the Ranger on adapter pin count. GM splits the Colorado on how many ports its body control module has. Toyota splits the Tacoma on the size of the screen.

There is no single rule. So here is each one.

Ram 1500 and 2500: the hardest of the lot

Ram trucks need two separate decisions, and getting either wrong means the module will not work.

First, the CAN-Bus type. Ram moved to CAN FD partway through 2024. Trucks built up to 04/2024 use regular CAN-Bus. Trucks built from 04/2024 use CAN FD. These are genuinely different protocols — CAN FD carries up to 64 bytes per frame against classical CAN’s 8, at a much faster data rate — and a module built for one cannot read the other. This is not a question of being close enough. A classical-CAN module physically cannot interpret a CAN FD frame.

Second, the cluster connector. Independently of the above, Ram fitted two different clusters:

• Analogue — 20-pin brown connector
• Fully digital LCD — 18-pin black connector

The colour is the quickest check. Brown means analogue, black means digital. The Ram 2500 Heavy Duty has its own module separate from the 1500, so a 1500 part will not serve a 2500 even with the same build date and cluster.

Four combinations, in other words, and your truck is one of them. More detail in our Ram 1500, 2500 and TRX guide.

Ford F-150: one clean split

Mercifully simple. The F-150 splits at the 2025 model year: one module covers 2017–2024, another covers 2025 onwards. Nothing else to check beyond cable length.

Worth knowing if you have been comparing prices: the 2025-onward version costs more, and that is a genuine supplier difference on the newer part, not an upcharge for the cable. See our F-150 guide.

The F-150 Lightning is a separate product again — the electric truck does not share the combustion truck’s module.

Ford Ranger: count the pins on the adapter

The Ranger splits on adapter type rather than anything you can see from the driver’s seat:

• 26-pin adapter — 2015 to 2022
• 16-pin adapter — 2022 to present

Because 2022 appears on both sides of that split, the build date matters for Rangers built that year. Check the door jamb sticker.

Chevrolet and GMC: generation first

GM’s trucks are listed by generation rather than by cluster, so you are choosing a product rather than an option:

The Silverado and Sierra generations overlap on calendar years because GM ran old and new bodies alongside each other during the changeover. If your truck is a 2020 or 2021, the body shape decides it, not the year.

The Colorado’s split is unusual: it is distinguished by the number of ports on the body control module, 7 on the earlier generation and 8 on the later one. If you are unsure, the model year is a reliable enough proxy — 2023 onwards is the 8-port generation.

Toyota Tacoma and Tundra: screen size and cluster type

The Tacoma has three versions, and two of them are the same generation:

• N300 — 2015 to 2023
• N400 with 7-inch display — 2023 onwards
• N400 with 12-inch display — 2023 onwards

So for a 2024 Tacoma, the year tells you nothing useful. Measure the screen.

The Tundra splits three ways too: 2nd gen facelift (2014–2021), and then two versions of the 3rd generation separated by whether the speedometer is analogue or full LCD.

Honda Ridgeline and Nissan Titan

The Ridgeline splits at the 2024 interior facelift — pre-facelift covers 2017 to 2023. The Titan takes a single module across 2016 to 2024.

Frequently asked questions

How do I tell if my Ram has CAN FD?

Check the build date on the driver’s door jamb sticker. Up to 04/2024 is regular CAN-Bus; from 04/2024 is CAN FD. The model year on the registration is not reliable here, because 2024 model year trucks were built on both sides of the change.

Will a mileage blocker work on a diesel truck?

Yes. The module reads the odometer signal on the CAN-Bus, which is the same whether the engine is petrol or diesel. Heavy-duty variants such as the Ram 2500 do use a different module from the half-ton trucks, but that is a cluster difference, not a fuel one.

Do I need the short or the extended cable on a pickup?

Most truck installations are fine with the short harness. The extended cable with quick removal is worth having if you want to be able to reach the module without pulling the cluster again — more on that in our cable length guide.

Does the trailer brake controller or tow package affect fitment?

No. Towing equipment sits on a different part of the vehicle network and does not change which cluster module your truck has.

My truck is a 2020 Silverado. Which generation is it?

Either. GM built the 3rd and 4th generation Silverado alongside each other. The 4th generation has the squarer front end and the larger grille; the 3rd generation body ran to 2022 in fleet and work-truck form. If you are unsure, send us a photo of the front of the truck and the cluster.

If in doubt, ask before you order

Trucks are the category where we most often get asked to swap a module, and almost always it is one of the splits above. Send your model, the build date from the door jamb sticker, and a photo of the instrument cluster. We will tell you which version you need.

Responsible use. These modules are supplied for off-road, motorsport, dyno testing and vehicle development use. They must not be used to alter the recorded mileage of a vehicle being offered for sale. In the United States, 49 U.S. Code § 32703 prohibits disconnecting, resetting or altering a vehicle’s odometer with intent to change the mileage recorded. Please make sure your use complies with the law where you are.
