Hi, I am trying to wire up an illuminated entry on a 2000 Rodeo. The alarm system is a Code Alarm CA-6551.

I have connected and programmed the Aux output, which sends a ground signal when the alarm is disarmed for illuminated entry.

The problem is, I hooked up the Aux wire to the vehicles dome light wire. Which I am already using on the Door triger input wire.

So now when I close any door right after illuminated entry (dome light still on) and arm the alarm, the system thinks that a door is still open.

How can I wire them up to both use the door trigger/dome light wire? I have diodes and relays laying around.

Here are links to the Code Alarm manual and Isuzu diagram. Thanks for any help!

Use a relay 85 aux 1 from alarm
86 12 volts
30 ground
87 to RED / green from car (door trigger)
program aux 1 for dome light supervision (bank 3 #6)

Go to where you've connected your door trigger, then between your door connection and the dome light, wire in a 1N4004 diode, band towards the connection then immediately after wire in your aux to the door switch wire that way the alarm doesn't "see" the dome light being triggered.

Except.... our first poster might need a relay to boost the current on the aux output!
