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 stuff4cars. 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. I actually drive a Giulia Quad, and that is difficult enough to get to the SGW. From what I have learned, the Stelvio is in a whole different universe of difficulty so this concept would be a bigger assist for Stelvio owners

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 on the Giulia forum, here: Other SGW post

In the meantime, I purchased a start/stop controller from Alfissimo for my car, which came from a company called 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 vehicle.

Thanks for reading!

Hello there, here is Leszek from STUFF4CAR. I wanted to let you know that I have built single loom prototype (for now with short 5" cables, final will be rather 10-12" and dual plug/socket set -12 pin and 8pin). I posted more information in here:
SGW Bypass - Patch Harness Solution!!!
If you are interested it should be available in following weeks, either through my US distributors (Alfissimo & Centerline) or directly.
All the best

bit of update, we are nearly at starting first produciton batch of SGW extensions - Stelvio users may be especially interested due to hard access location of SGW in hardly reachable location:

pre-production loom extensions looks as below - 10" extension made with top quality cables/connectors/sockets and proper finish and testing or each single manufactured set:

Last week I installed two pairs of SGW extensions in customer's 2019 Stelvio. First retrofits were done with SGW bypass (on pictures cables and SGW shown as not yet in final position), then I removed bypass, put extensions into final position (on other side of radio headunit looms and around one main loom routed nearby), so they are safe & not rubbing on any metal edges etc, and joined together the cables + used zip tie to secure them in such positon. Any future needs of installing SGW bypass will be 3 minutes job, as now it is only glass compartment to be removed and user immediatelly gains access to SGW extension cables. Extensions are available in US from my distributor Alfissimo International or directly from my webshop. A few photos for ilustration below.

For the initial install of the bypass cables in Stelvio is everything accessible thru the sunglass compartment removal or will I have to remove bottom panels to move radio unit?
I am eager to do this so I don't have to depend on a dealer for regular service.
It is wonderful to have specialists to develop the tools we need to work on our vehicles.
Thankyou

can't imagine without removing bottom panel, access to SGW in stelvio is difficult. radio also goes down, once I did stelvio without disconnecting radio, but that is not best IMHO (cables pulled stressed all the time with radio hanging on them) - all jobs now I do with radio unit out (just do not break radio connectors - a lot sits tight, and each requires proper lock release first).

small add-on to above post, today I had Stevio in garage, I tried again without disconnecting the radio, I only manouver it to side and rotated it was quite OK and saved me probably 10-15 minutes on whole labour + no risk on braking anything + all looms left orgiginal route/order

Thanks for the update I appreciate the information.

Thanks for the link Alfissimo. I will be buying the whole kit in the spring. I just got soaked by the dealer for $200 for just an oil change. They were nice enough to reset the 2 year service counter also since I am under 5000 miles.
I will be doing my own maintenance from now on.

I just ordered mine! I've never used MES, SGW bypass, so this will be my first time doing something like this on my alfa. I'm tired of going to the dealership so here's to hoping I can get it setup myself!
