    Any idea how I can get a large cable from the cabin into the engine bay?

    I've searched a few different topics but I haven't found a solution yet.

    Here is what I'm trying to do:
    I have a Goal Zero Yeti 1400 mounted in the back seat area. I use it to power my fridge that is also mounted in the back seat area. The Yeti will power the fridge for about 4-5 days and then I need to charge the Yeti unit.

    In order to charge the Yeti unit I purchased a system called Yeti Link. This allows you to charge the unit off the truck battery.

    The problem that I'm running into is that the cable that connects to the battery is too large to run through the firewall.

    I will likely need to drill another hole or run the cable through another source, in order to reach the battery.

    I wonder if it would be possible to charge the Yeti by using a portable battery jumper?

    It would charge but it's not as efficient as the Yeti Link. The Yeti Link will allow 300-600watts as oppose to other plug in solutions.

    There is a large rubber grommet under the center console. I ran my GMRS antenna line through it to run to my bed rack, its dead center on the front seat line. I just used a drill bit and drilled though it ran the wire and put some silicone around it. The rubber is wide enough you should be able to pass any large wire through. To access the grommet just pop off the kick panel on console, pop off the top where the gear shift is, remove the four bolts at the bottom of the storage area and the storage area will fall back and you can access the grommet.

    Ok, how thick is the cable? Is the problem the cable thickness or the connector/plug? If the issue is the connector/plug I would be inclined to cut the cable, run it into the cab and then reconnect the plug. But that's just me...

    Perfect! Thanks for the details. This sounds like a solution for me.

    Yeah, the cables are pretty thick. About the size of normal battery cables inside the engine bay. I was going to use the grommet on the drive side to enter the engine bay but it's not big enough. I'll use the recommendation from Grendel.

    You could also go under the frame then up through the floor grommet by the rear door. Easier to check that you've resealed it properly and of not there's at least no fumes coming from the engine bay.

    I'll have to check this rear floor grommet. Will it be under the seat area or back up against the cab?

    I was never able to find the one on the floor under the rear door. I did find the one on the floor under the center storage. It was easy to access from both top and bottom. I probably didn't make it clear that it is not through the firewall but through the floor underneath the center storage.

    There is also a large floor grommet under the passenger side front carpet, used it to run my power tailgate cable. Not sure about ones in the back seat area but easy way would be to go under the truck and find them.

    I believe they are under all 4 seats, I have used the 2 under the rear seats. Not the easiest to get to but not bad, just be patient

    The grommet on the firewall should have a large nipple on the bottom of it. Just cut that nipple off and you should be able to run large wire through it. I ran the wire for my amp through the driver's side grommet.

    @codename607 For what it’s worth. Here are pics of the grommet I went through 775D10BB-BF43-45E1-ADA1-AA71D617EB21.jpg17583A70-BF2D-44B7-AFD5-C458F86C280F.jpg
