Hello All,

Like many of you, I am having to deal with the security gateway module in my 2019. the simple solution is to use a effective bypass module like the one sold by Alfissimo which I believe is manufactured by a company called stuff4car. For me, I do not want to operate the car with the bypass in place, only to use it when needed for code clearing, simple oil reminder resets, etc. So that means that the connectors on the harness side and SGW side would be exposed to repeated cycling off/on which is not what they were designed to do. Having encountered problems before with electrical plugs failing after such cycling events before I went to install a SGW bypass I wanted to have a solution that will protect the OEM plug and module and put all the wear and tear on a replaceable part - and, as well, remove all of the headache involved with removal and re-installation of the SGW or bypass module.

Enter the SGW Patch Harness. What the patch harness will do is to connect to the car side harness plug with one assembly, and the SGW module with a second assembly, and these 2 harnesses will have compatible plugs to the car side harness and SGW module. So, for example, with both components connected together and to the vehicle, the vehicle is operating exactly like OEM. Then, when access to a service tool is is needed the harnesses can be unplugged from each other and the SGW bypass can be connected to the car harness-side patch harness which will then bypass the SGW like would be normally done. Finally, if restoration of OEM controls is desired the SGW bypass can be conveniently unplugged from the patch harness, and the 2 patch harnesses can be reconnected and full OEM function is returned.

Benefits of this are

(1) very minimal impact/wear to the OEM connectors and module - which are not designed for repeated cycling

(2) ability to maintain OEM controls if your vehicle makes a trip to the dealer. Obviously, if they pull the dash down they will find the harnesses but IMO that is unlikely and less problematic then if your vehicle is detected to have a bypass installed

(3) no big effort to install and remove. Once the patch harnesses are installed there will be some extra cable length that will be accessible under the steering column area. Just pull it out and unplug/plug in etc. and return the extra cabling to under the dash when you are finished.

So, the hangup up to now is that such a part has not been mass produced. I actually started a thread on this awhile back, here: Other SGW post

In the meantime, I purchased a start/stop controller from Alfissimo which came from stuff4car. I was really impressed with the quality and functionality of this part, and thought - if they can make something like the S&S controller, maybe they could make a patch harness to work alongside their SGW bypass module. So I reached out to them, (SHOP STUFF4CAR) and recently I have been in communication with the company owner who has agreed to produce these harnesses. I am going to buy a setup regardless, however if others also want this then the cost will go down from larger production scale. Right now, the cost range is around $200 (for a single production set) but could drop $40-50 lower if say, 20 people ordered. The exact cost down is not confirmed, however.

So, if anyone is interested in this solution please reach out to stuff4car via their contact us link. I'm not going to post the link here but you can find it easily on their site. After a couple of weeks go by, based on any additional interest a final price can be set. Note that I am not affiliated with this company in any way. I am only proposing this based on the high quality of stuff4car's existing parts that are similar in nature to what I am looking for, and my desire to obtain this solution for my personal Giulia.

I'm going to throw this up on the Stelvio forum too, since apparently access to the SGW module in the Stelvio makes the Giulia feel like a stroll in the park by comparison - so hopefully there will be a good response from that crowd that will knock the price down for something that will help us all.

Thanks for reading!

Great idea. I was planning to speak to epsonix as well to discuss this but looks like you have gone much further. I am planning on upgrading my car to a 2019 so I will need one (in UK). I will send him a message. Cheers for the heads up.

I still haven't tested if it's possible to have SGW completely removed and how to that official dealer diagnostic equipment reacts
I tested that when I forgot to remove the SGW Bypass when I took it to the dealer for service. I guess WiTECH freaks out if the SGW isn't connected.

I'm more interested in removing it from proxi config completely not only disconnecting it and using SGW bypass. Of course it's more suitable for non-warranty cars.

Very interested, but the 'ballpark' estimated price of $200. USD seems a bit dear for what ought to be just some wires and a few connectors.
If a few get in, then the cost will drop a bit. But you also have to consider that the cables are being small-scale production manufactured using quality parts and materials. With labor time and materials, plus some reasonable profit, even $200 seems fair IMHO.

Hi Guys,
Here is Leszek from STUFF4CAR, I would like to use opportunity and comment on some of matters. Scale and quality dictates price. we are talking about niche models, and within this niche market product made in a few, ten, 50 units, but still requiring top quality cables, connectors, documentaiton, then here we come. Please compare plug quality on most of AR SGW original plugs with ones I'm using (sometimes AR used the same quality plugs, usually not (much cheaper/inprecise), sometimes one is the same one cheaper, never seen both top), and the socket quality. I would like to mention that there is number of processes involved to build such custom product - say on sockets and off the shelf housing to keep it compact (milling, laser cutting), again with far from any high volume production I do neither get subcontracting nor components for cheap. We do not manufacture in China, we do test every single units, we do inspect each during production, even I look regularily myself at what my subcontractors deliver or technicians do/how they this, just to make sure everybody stick to instructions and do proper/quality end user product. Machine made where it needs to be, hand made where this is more effective/better. For one year I didn't have single product return/complaint, and my goal it is to keep it that way, and still offer individual support for these who needs such.
On top of SGW extension harness, we plan to introduce a metal lever which will help to much easily remove SGW plugs out of sockets - for these who connect/diconect these often, or for Stelvio users (Where acces is not easy/not visble SGW plugs) that should help a lot in and SGW related jobs.
All the best
Leszek

Good, at this stage every single customer have noticeable influence on price I could offer. One question remains open on length preferrences - what lenght of cabling we do talk about? My feeling (I didn't ask my subcontractor yet), that leghth has low final price impact (at least in reasonable range), cable should be 8,10,12,15" or 20" long? would you see it sticking out with above foot cover installed so it is easily accesible? here I could (or should) think about out other cars like Stelvio where SGW is located in difficult area above steering wheel column, and the length to reach out of the plastic cover would be at least twice longer (rought guestimmete, I will measure when I have Stelvio next time in my garage) - if that is a goal for majority (is it?).
Let me understand your needs, so I will try to give you product you all like.
I have feeling some of Giulia owners may be happy with even single harness (as impact to original car loom plugs (usually average qualiy in my opinon), with sterss on pulling them out, may be more dominant reason, and not necessarily any long loom - this is for guys who will decide to daily drive with SGW bypass - otherwise dual extension lead to connect to SGW and unplug SGW bypass. However Stelvio owners, due to hard access to SGW location, may prefer dual extension harness always. Share me your thoughts please.

My feeling is that the harness length should be long enough to accommodate both vehicles, be long enough for convenient access to unplug/plug in SGW bypass, and not too long that it is difficult to stow into the under steering area. It probably also will depend on the stiffness of the cable, how tightly it can be coiled/packaged into the under dash area. Likely 10” would be enough based on the photos of SGW placements but ideally it could be verified with on-vehicle measurements.

12" would be plenty for me. I would prefer not having cables hanging out but I guess any extra cable can just be folded behind the panels.
I have left the SGW bypass on for almost a year now... I am dreading having to remove it for the oil change.

IIRC, a while back someone posted that in other cars it was possible to cobble up a second OBDII connector, which maybe could be done on the "far" side of the SGW. I wonder if something like that would be a viable alternative to SGW bypass.

Maybe this would make the SGW freak out, I dunno.
