Default Only front parking lights flash with alarm?

Finally have some free time to hit the community, and I'm going over all the little things I need to fix on my SC300, so bear with me =D

I'm guessing this one is easy: I installed my alarm using the Bulldog wiring references (found here: http://64.85.6.121/diagrams/diagram....7&link=BULLDOG) and I noticed that when I arm/disarm my alarm, only the front parking lights blink! The front bumper side marker, the front headlamp marker do what they're supposed to do, but there's nothing going on in the taillights. Short of running a wire from the alarm brain through a relay to the tail light parking (+), did I miss something during the alarm install?

You have to tap the wiring harness heading back to the back on the driver's side also. Mine did exactly the same thing. I can't remember off the top of my head which wire it is but I'm going to be pulling the molding soon. I can let you know then.

My Carbine alarm blinks the parking lights just fine - I tapped into the wire, no relay needed. I know on DEI systems, you need to set the relay polarity, and other alarms require that one or parking light wires is connected to power or ground while the other is connected to the parking light wire.

bump realized I still haven't solved this one yet.

BTW I'm using an Autopage, the park light output is + IIRC, no external relay used.

Most alarms give you an option of switching the parking light relay polarity - otherwise you'll need a relay to connect it to a - trigger as described here:

I'd find someone with DirectTechs access and have them print out a wiring chart for your car and compare it to the TSRM ETM diagrams - most of the wires you need are located on the wiring harnesses leading to the fuse panel under the dash.

Wait a second, are you guys reading the problem? The front parking lights blink correctly when I activate/disarm. The rear parking lights do not blink. It's not a polarity issue or anything like that.

Have you tagged the right wire that also controls the rear parking lights as well - hence why I said to check with the TSRM. DEI/Audiovox's wiring database isn't known for accuracy.

On my LS, I tagged the green/black or green/white wire leading from the junction panel to the rear lights with the - output. This was verified with the TSRM against the DEI diagram.

That's actually the wire I'm looking for, someone mentioned earlier that there were two wires but never got back to tell me =/
