Not for KTM dirtbike fuel pumps...
FYI, anyone who was directed to this part for a KTM fuel pump or lighting relay, the plug section fits, but the body of the relay is too large to fit in the OEM holder/mount. I have not verified it electronically yet as I need a relay that fits in the mount. 2013 KTM 500excf Still giving it five stars as there's no reason to negatively review it just because it doesn't fit my application, just sharing the information I found for other KTM owners.

My Fault
They didn't fit. Guess I wasn't thorough enough on the actual PIN size. I'm sure their a good product .

The Unsung Hero of My Car's Comeback Tour
My car went from “maybe it’ll start” to “vroom vroom” really quick after installing this little powerhouse. It’s like giving your car a shot of espresso — but waterproof and less jittery.

Easy to install and replace.
Easy to install and the same size as original.works good for the money spent and can keep the other as a spare. Completely compatible with same pins as the OEM part.

Starter relay
No it did not the pins on these relays are to big, even though the fitment for the item says it would have fit, correct amount of pins, its just that the pins are to big and do not fit in the spot inside the fuse box on my father in laws truck

Smack 'em
I almost returned these until I discovered that you have to smack the top on a hard flat surface to get them to work.

Blades are smaller making loose fit
Blades should be wider so they fit tightly like factory so not to cause overheating of the terminals. They worked but concerns of loose fit.
