200 ma enough?

Blimey over here you can buy a DMM with hold for under $50, its enough for this job.

Honestly, I think you should just verify that you've got the correct trunk relase wire and connect it. I've never yet seen an alarm aux output that couldn't activate a relay circuit on a car.C Renner's Auto Electronix

Thanks guys,  Got the alarm installed and it works great.  You were right chriswallace187, it works right off the alarm without a relay.  There is one problem though....when I dissarm the car it unlocks the doors but it also pops the trunk.  Remotely poping the trunk does NOT mess with the door though.  Any ideas?

It may help if you tell us what alarm you put in the car - only one guy on this site has a crystal ball and he has yet to post in this thread.Kevin Pierson

It won't surprise me at all if this is a Scytek alarm, since I've had exactly the same problem with one. Try using a separate relay activated by the trunk release output, wired as follows: 85: (-) trunk release output from alarm 86: constant fused 12v+ 87: ground 30: trunk release wire on car That worked in my case...I assumed that for whatever reason the unlock output and trunk release output weren't isolated very well on the pc board, and there was just low enough resistance to ground to activate the trunk release circuit on the car when "unlock" was pressed. Definite design flaw in that module(and I tried a spare brain with the same results) but it was easy enough to work around.C Renner's Auto Electronix

The crystal ball is down at the moment.  Sorry.

Er I think we just came round full circle, that's what I suggested on the previous page Chris! Here's an alternative though to completely isolate it:- Trunk trigger from alarm to 85, constant 2amp fused to 86, existing wire, car side 87a, trunk side 30 and good ground to 87.

Do you think it's getting the stray current from the BMC of the car?   If I'm understanding your wiring suggestion correctly.  I would have thought it would be in the alarms brain.
