Hi I'm want to retrofit the alarm on an Alfa GT.
Finished installing the siren and the volumetric sensor, but now I need to activate it.
Can somebody tell me the proxi byte/s that need to be set to enable it ?

Current proxi config is:
36 30 36 39 33 34 39 36 20 20 20 50 50 45 41 43 45 45 45 53 49 20 03 06 20 CB 15 00 00 09 05 00 00 13 00 00 82 06 00

Thanks.

Can be closed it was solved,

Apparently there are 2 types of body computers on GT''s one that support alarm and one who doesn't.
Looks like all GT's that have headlights washer, have the body computer that supports the alarm function.
In the end I had to replace the body computer with another one to make it work.

To enable it you need I set in byte 38 bit 4 to 1.
