    Had anyone here spliced their rear sensor extension cables?

    I have to run through the hatch grommet but the connector isn't going to fit. Just wondering if anyone has had any issues splicing the extension cable.

    It's a hose similar to the pic below that I have to run through. It's packed with wires with just enough room to fit the wire in.

    Why not trim the grommet and use duct tape? I wouldn't cut the connector as it is necessary to make it water proof

    The splice would be done in the interior. No worries about water coming in. Not sure I get what you mean by trimming the grommet and using duct tape.

    I would cut the extension cable about 12 inches from the end. Run it through the grommet and down the side panel into the lower hatch area. Then I'd splice it together.

    The "hatch grommet" :airquote: should be made of rubber which can be cut just enough to fit the connector

    It's too tight with the other wires that run through it. I tried last night and didn't have enough room for the connector itself. The wire will fit through just fine.

    Not familiar with that car but I believe you can take off the panel and the grommet then run it together.

    Take it to a 12V guy if you're not comfortable with doing it. The guy near me cuts every cable he installs so there's no slack. I doubt you'd pay more than $50 to do 2!!

    I'm a 12v guy ;) I have extensive experience with car audio and security.

    I was just wondering if anyone has had any issues with spliced cables on the ALP. :)

    Yes, I cut my extension cables for both my ALPs and my Radenso RCM rear antenna. The rear hatch grommet is FULLLLLL of wires and must remain water tight so cutting it is not an option. I used RJ45 heads to reconnect the wires rather than soldering them. I have had no issues for about a year now. Check out my Jeep install guide.

    [doublepost=1520946229,1520945726][/doublepost]Actually, I think I used RJ12 and cut the actual ALP head wire, but the end result is the same. Most high-end shops will also cut wires and reconnect since it is often the only way to get those fat heads through an opening.

    I highly recommend only cutting the RJ12 off and running the wires threw that way then recrimp it. Cutting the wires then resolder may cause error code.

    I have to do it on the extension cable. The primary cable only reaches to the rear cargo area.

    @LuCroix on my front install I was able to run all 4 wires through a grommet with a hole smaller than the size of a #2 philips screwdriver. I used an old pen disassembled so that one end would fit over the connector. Then the tapered end of the pen easily passed through the grommet with the help of silicone spray.

    I agree 100%

    EVEN better Dont cut at all Get an angled or get access to the grommet and hole and GENTLY open up the space with a phillips screwdriver
    Use a medium size first then increase the size GENTLY moving side to side.

    DO NOT PUNCH THRU ANY WIRES !!
    FINESS is the key word here.

    Done it hundreds of times. From Jeeps to BMWs to Benzs to Crown Vics to boats.

    Anyways thats how i always do it.

    It's not a rubber grommet like the firewall. It's a rubber hose with a bunch of wires already in it.

    There is absolutely no way to get the head of the ALP cable through the hose that connects the rear hatch of a 2017 Jeep without serious risk of cutting one of the 60 exposed wires already there, and I would assume that many other vehicles are the same. Even with that risk, I don't think there is physically enough room to make it work.

    Cutting the wire is not rocket science and will not affect the performance of the ALP system when done correctly. Honestly, I didn't give it a second thought, and any high-end installer wouldn't give it a second thought either. It is much easier to replace a screwed up wire or complete head for ALP than it is to try and fix a cut factory wire buried deep in the body of the vehicle.
