Are SGW Extensions Necessary?

[Terrymo]

These are what I need to disconnect and connect my cables to, right?

Buy the ECRI module, the holder and no need to use extension cables. Unplug once and plug into ECRI. Now anytime you want to make adjustments or even clear a cel no need to remove the cables.

I personally don't like keeping the SGW bypassed permanently, but to each their own. I also tried that holder; the 3D printing was pretty poor with visible gaps between a couple of the layers. When I attached it to the pictured screw, when I put my plastic trim/cover back on it snapped at one of the layers with a gap.

I had no issues with mine in the 2 years I’ve had this setup. I know 3D can be hit and miss. Definitely sounds like you got a bad one. I don’t mind mine being permanently bypassed since I don’t use the dealer for anything. I use an independent if I need work done I can’t do.

After seeing this image I understand why some of the threads said getting to the gateway was going to be a pain. I don't have that module behind the diagnostic connector or the amplifier (?) to the right of the SGW. Mine is a no-option Sport; it took me longer to get the camera to focus for the pic I posted of the connectors than to disconnect them.

Ran out of daylight so I didn't get to install the tires, but at least I know I can get to the SGW very easily in my JL.

Thanks again for all of the help and quick replies!

I got the extension cable because without it you have to do a lot of wiggling and pulling of two very tight connectors that are in a hard to reach place and each connector has a lot of small gauge wires. I was more concerned about damaging the wires than damaging my fingers.

You may think you'll only need to do disconnect the SGW once or twice but, if a 2018 is the same as 2023, you'll need to do it anytime you want to do diagnostics (other than simply reading codes) or to reset codes. Keep the extension cable plugged in all the time. That is its purpose.

Mine split between two layers and I sent a pic and the Etsy vendor ClickonPC immediately sent another one no charge

That pic is easy compared to the 2024 arrangement. Green arrow points to the SGW connectors, red arrow points at the black bar that seems new in 2024, blue arrow points to alpine premium system amp. That said, I managed to get them out, put in an extension cable, and never again.

UPDATE - I bought some of the more budget-friendly versions of the extension cables; I knew I needed to order at least one for my son's loaded '20 JLUR, so I decided to get one for mine too just to make future changes easier.

I got the cables disconnected relatively easily on the JLUR - index finger to depress the tab, and a long flat blade screwdriver to use as a wedge between the outer edge of the SGW and the flat outer area of the plug. No harm to any of the wiring or connector doing it this way. I managed to squeeze the extension cables in after a few minutes with minimal blood loss (small hands haha). It is a tight squeeze though with the extra modules in there. Mine felt like I had a mile of space to work with . Once that was in, I fired up the Jscan and toggled the paddle shifters on for him since he put in a 392 wheel. Definitely glad I got the extension cables, since we never know what the future holds for us and what mods we might decide to add down the road.

Thanks again for the recommendation!

Every time I tried to disconnect from the SGW, my hands ended up with some scratch wound. Ever since the extension cable, all good.

It depends how much you like cursing, bruising your hands, and contorting your body in unimaginable ways to disconnect the SGW connectors from their origninal location.

EDIT Although I will say that the 2018 are much easier to access than the 2024's, but still a PITA. But NO, you do not need the extension cable. It just makes life easier the next time you need to connect.

Hi there, if you take your jeep to a dealership and before that you unplug the stock SGW cable from the back of the OBD2 port, and just leave it hanging hidden for next time use with the bypass OBD2 adapter cable, will the dealer still can do a diagnostic?
