Yes it will be start in 90% cases as alarm is disabled
If it doesnt then you are just removing connectors from the box not disabling the alarm so you can always plug them back if something goes wrong and it will be as before dont put the module back for time being in dashboard
I have already done this before once on a steelmate alarm when the remote battery died and car would not stop screaming
After unplugging connectord i was able to use the csr as normal before i got it fixed
