Tricks for running wire through firewall?

Where is everyone running wires through the firewall on their '14s? Access is very limited under the dash. The big harness on the driver's side would be nice but I couldn't find where my snake poked through. I'd like to avoid drilling a new hole.

There's a big rubber grommet next to the steering column. Cut the nipple protrusion and fish your snake thru. It will come out above the parking brake

Thanks, that's the grommet I was looking at. I'll give that a shot

Unbolt the black box next to the parking break and you'll have just a little more access to it.

Be careful coming in... go slow. It helps if you have a 2nd person on the footwell side to see when it comes through. I did mine solo when I installed the Kicker VSS system (needs power ran to the battery).

 

If you feel resistance or hit a wall, you're probably hitting the back side of the X61A Junction Box. That's the box with the black cover mentioned above... next to the E-Brake.

 

If you're using something like a coat hanger, put some electrical tape on the tip to protect and wires as you come through.

 

Good Luck!

I ran it through the grommet next to the steering column as so many others have with no issues whatsoever. Now my music is rocking :nopity:

On mine there was another grommet within the bigger grommet. Once i removed it from the inside i had no problems getting O gauge wire thru. Unbolting the black box will give you just a little more room to get in there.

The grommet will self seal tight to your wires, i taped my wires onto a sharpened piece of coat hanger and made a new hole beside the wiring harness to avoid poking a wire in the harness. Still tight as a virgin after 2 years.

I cannot for the life of me get through the firewall.....I cut the little access hole by the drivers side, moved the black box, even was desperate and asked the wife to push the wire in. I hear it, just cannot find it. 

I am no contortionist to get my fat a$$ under the dash, so this is really make me mad. This is all I need to complete my 30” rough country led bar and x2 8” led reverse lights.

      OCI, not when but why?

      By KARNUT · Posted

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.
