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!
