The alarm is the original Becker that came with the vehicle and as for the FPR. I know it was changed once. I know where it is located, but how to I check the amps (which pins and readings)?

@ Two560Two - The door panel to the alarm system is on the passenger side floor panel against front wall (basically if there was a glove box it would be located underneath). There is an access panel with a 8 or 10 mm nut.
