There's one on the driverside that's much easier to access.

 

^^^ as stated above, there is a good sized one on the drivers side, you will have to move some of the "foam" on the fire wall to accsess it, but its just a flap. You can see through the engine bay, its on the left side of the brake master cylinder pretty high up on the fire wall. I ran 1/0 gauge through it no problem. Just make sure you use a gromet, and put an inline fuse before the fire wall. good luck

 

well I did was drill a hole through the fire wall right above the kick panel for the ecu it came out right under the charcoal canister then I got a grommet and put it in and it was all gravity

 

appreciate the help
