I know where it is on the 2nd gen but where is it on the third tks

Also what's the alternator output on the 2nd gen and 3rd gen Ty guys and gals

 

Are you asking where to run the wires in a 3rd gen tl?...just trying to clarify the question

 

Yes sorry I wasn't specific

 

You can always do a search but for mine I ran it underneath the back seat then underneath the plastic pieces on the floorboard/where the door closes up to the driver area. Then try to feel around up to the left of the brake pedal and you should find a rubber grommet which runs into the engine compartment. I ran a 0 gauge wire through that hole with a little cutting of the grommet. Once you get it through the hole just run the wire in the engine department however you want to the battery

 

Not sure on the alternator output though

 

Just is what I did. Makes a real clean install

 

I found that grommet but couldn't find the wire in the engine bay, so I used the grommet in the driver floor board.. Still looks clean
