1) when I attempt to arm the alarm, the security light does not illuminate unless I disconnect and reconnect the battery (or pull and reinstal fuse #1). The anti-theft will arm and disarm without issue from that point forward, unless I turn the key to the on position. After turning the key to the on position, I have to cut power to the entire car as stated above to get the security light to come on.
2) upon arming the system, I attempt to trigger the system (hood, trunk, and door switches work). The only reaction I get from the car is that I can hear the passing relay click. No lights, no horn.
I suspect the etacs unit, but all other etacs controlled functions on the car operate as intended. I have a spare etacs (untested) that I swapped in, and it behaves the same. Also swapped the passing relay, no change.
I've consulted the fsm and the troubleshooting guide for my particular set of issues isn't outlined. Any insight would be appreciated.

For the second, the passing relay should activate the passing control relay inside the cabin of the car to open and flash the headlights. The horn relay is located on that relay cluster of 4 above the coil and should activate independently of the passing relay. Take a look at the diagram on page 8-288 of the manual. Note the passing control relay and horn relay feed back to the ETACS via connection 29 (Tr2) through two independent diodes. It just seems like the ETACS doesn't know the system is fully armed. As to why it partially works after resetting the battery, I'm clueless.
I'd start with those door actuator switches. I've had problems with those before. (I've also had issues with the key cylinder switches but I don't believe that is your issue). If you can get the alarm to arm correctly, it may resolve the second issue you have.
