Well, 5-wire is typically to reverse polarity to a motor to move it one way or another, like door locks. With one side of the motor permanently resting at ground there is no reason to treat it as a 5 wire imo.
My factory and aftermarket remotes still pop the trunk....

Further info - all, and I mean every wiring guide I found, is incorrect, the Trunk wire is NOT 5wire, its + pulse, thats it. Vacation pics confirm, the trunk is grounded on one side of the motor an the other is + pulse. You still need a relay because most alarms offer trunk output as a - pulse. This is still easier to wire up now because there is not cutting of the factory wire.
Also - I would NOT use the net. safety wire to drive a relay - it appears to be EXTREMELY low current from the ECM, It may be safe to use the - when in gear, but don't rely on the + signal when in neutral, ask me how I know!

FYI - according to the vacation pics, and my testing, there is no factory alarm arm wire available, its some sort of data/etc interface not a simple pulse.

I use to work at Clarion - I'll see what I can dig up for you :-)
Also - check the install instructions posted here, there is a good picture of the harness in there that may help the dealer find the part #.
