The SPE Motorsport 6.7L Emissions Harness Plug is designed to protect and seal your emissions connection on the ECU when exposed to the elements.
Creates a perfect seal inside the ECU cavity protecting it from the elements, moisture, fluids, etc.
Prevents corrosion to ECU pins
Made from b-nitrile material which is resistant to corrosive substances such as fuel, coolant, etc.
Great for use when removing the DPF for cleaning/servicing, etc.
Small, compact, clean design
Simple, easy install
The plug creates a perfect seal within the ECU cavity providing protection to the ECU. Made from b-nitrile, the harness plug is resistant against corrosive substances such as water, fuel, coolant, etc. When the emission harness sensor plugs under the truck are exposed to the elements around it, corrosion can occur. When this happens the harness can corrupt the information that the ECU monitors causing codes, check engine lights, and electrical issues. This simple solution will provide protection and prevent expensive repairs.
Easy to install put a little di electric grease inside and a thin coat on the outside and it went in with ease.snug fit.
Great product just as advertised. Thanks
Perfect plug to fill that blank spot in my pcm. Must have to prevent corrosion

Works just as advertised

Great fit. Good product!
Finally something to protect the ecm!
Perfect fit !!!
The ordering process and shipping updates are much easier
This plug is made of good quality material and fit snugly into the receptacle. It is exactly as advertised.
Easy to install great quality as expected from an SPE product and fast shipping definitely recommend it for your powerstroke
Good quality and easy fix. Thanks
Called, placed the order, parts showed up.
With all the shipping problems going on today, they delivered as they claimed.
Love the product
Fits like a glove
It's a solid piece of rubber that fits really tight. I don't see anything getting in the computer even if you have dummy plugs this will also give you a piece of mind.....
Great product! Quick delivery!!!
Made with quality just like everything else SPE makes
This product is a one and done piece. The alternative product is a 100 dollars in plastic caps, and while they might be nice, it’s a little excessive. I like the fact that I can unplug my emissions harness in order to preform maintenance, and can put something in place of it to protect the ecm.
Super fast shipping. Got my product in 2 days. Fits nice and snug exactly how it is expected to fit.
Awesome simple modification to get rid of all the open connectors hanging from the bottom of the truck! I do wish it came with the inline 110 dummy plugs for the reductant tank harness but I'm glad to have this plug!!
does its job perfectly. fits nice and snug as well. purchased this to test the harness/pins without getting the female end dirty.
Fits as perfect as all their products. No extra codes or anything.
Coolest little idea ever! I put some dielectric grease on and made a perfect fit
Product was shipped quickly and packaged well. It was exact to description and fit just like described. Would recommend this product to anyone that needs to protect that port on the ecm.
Looks great fits great
Another great product from SPE.
