So if I replace the CDR23 in my 03 996.2, (it has the MOST fiber optic system), with an aftermarket unit, will the alarm system still function correctly?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Yes it will. I believe there’s a wire that attaches to the OE radio that needs to be grounded for the alarm to function. It has been a long time since I had my 996 system updated, but it’s a brown wire, as I recall.

Yes brown wire with blue stripe, needs to be grounded for the alarm to function.
