I'm in the process of removing of what appeared to be a jank *** dealer installed security system but upon further inspection is factory? There were some wire splices, relays, self tappers, and butt connectors that looked pretty questionable but this popped up in a Google search and it looks like a factory option.
There was also some weird pigtail extention between the ignition and main harness that had a relay in between that I removed.
Anyways I was wondering if anyone had a pinout available before I start ripping out anything I don't need or if I can even remove any of this stuff. I don't really care about the alarm system as long as the power locks and immobilizer works.

That's not the immobilizer module, which is a Lucas/TRW device. This looks like a Mazda-branded car alarm. These were sold as accessories, and could be installed by the aftermarket industry or by dealerships.
Interesting, I'm going to try and rip out as much as I can and hope my car starts lol. Just got my block and head back from the machine shop so it'll be a while before I find out.

This.
The immobiliser modules that I have seen on ADM NBs is located up under that troublesome centre dash bolt. I have sold off about three sets of ignition lock/immobiliser/ecu, as I recall all three are linked and needed to get the car started. USDM may be different though, but I will bet my shirt that that is nothing to do with immobilising, and all to do with dealer installed anti-theft.
