What is best access point for running wire through firewall?
 

What is the easiest access point to run wires through the firewall to the engine compartment from driver or front seat passenger area? Best for me would be near glove box as that is where I want to end up. Detail will be much appreciated!

There is a grommet on the driver side firewall right behind the shock tower. Peel back some of the tape from the wires in the engine bay side and fish a coat hanger through there. Some have poked a hole through the grommet, that works too. Remove the black plastic panel in the driver's foot well and you should be able to see the hanger sticking through. I'm sure there is another on the passenger side, but it might be trickier with the ECU box there. You shouldn't have too much of a problem fishing the wires from the driver side to the passenger side, just remove both foot well panels and the radio and/or climate controls.

I concur with Relentless. If you can fish passed the ECU, then it will be a home run to the glovebox. Just curious, what are you wiring?

Thanks, found the grommet on passenger side after I removed the glovebox, works best on that side as want controller for Meth/water injection system in the glovebox.

I am going to let the tech expert finish up the install as he is also doing a nitrous system at the same time.

Should have it back sometime Friday if all goes well.

Nitrous?! Hhhmmm ....

Yea, won't be the smartest thing I ever did but hopefully not among the worst.
Being very careful to include all the safe guards.

Not meant to be negative comment. Just couldn't remember anyone else doing it here. I don't have much knowledge on nitrous.

I assume there are ways to implement it with different power levels without touching the bottom end?

Just to let you know I do have an N62TU motor with 20k miles for sell,,,just in case..LOL

Didn't take it as negative, it is at least a little out there. We think we can go to 150HP shot with reasonable risk. We are OK if we get to half that so I think we have reasonable expectations. This will be on top of Dinan exhaust, throttle body, air flow sensor and stage 4 engine and transmission software so some of the mods in place will facilitate in and out flow. We will know but end of day Friday if we get what we expect with some safety margin for the bottom end as we are not modifying anything more than already in place.

Thanks for the head up on the used motor, did get a snicker but not a LOL
