I ordered a Bully Dog Triple GT tuner and I read some where that it needs a fuse or some crap. I only saw this at one site in a review is this true or will it just plug and play on my 4th gen Ram 1500?

 

It should come with its own OBD2 adapter, and with that should be its power wire, and in that power wire is a fuse. You can plug it in and switch it over to use the power from the obd2, but personally I would rather it have its own power source. Up to you, you just don't know about surges with these new computer systems.

 

 

Regarding the above mention question, I just did the install to the power block/fuse box under the hood. Ran the power wire to the USB interface 10 amp fuse in order have the unit turn on/off with key. Seems to work without issues (drive way test/run) any issues with the way it is ran? Tried to ensure that the used fuse would not have issue with other systems.
Thanks
