Avital Avistart 3200 Trunk Release

I seem to be in a bind.   I dont understand what the problem might be with my setup. I have a 95 Grand Prix

The target wire is a BLACK/ WHITE at the trunk release switch. You will need to give this wire a momentary ( + ) signal. If your alarm / remote starter does not have a ( + ) output trunk release wire, you will need to install a relay that chages polarity. Wire up a relay like this:

• 86 + 87 - 12 Volts Constant
• 85 - trunk release wire form alarm or remote starter
• 30 - BLACK/ WHITE trunk release wire of Grand Prix

I have wired my SPDT Bosch Relay according to this information.  The problem that is occuring seems to be not enough negative pulse from the control box.  Im using the correct wire, and it works properly with the remote.  I get a negative signal when I press the trunk button, but it doesnt seem to be enough of a negative signal?  When the RED / white wire from the remot starter's control box is activated, it will drop the voltage from ~12.7 to ~10v.  Does this seem right?  when I ground the terminal out on a screw the relay clicks no problem, but nothing happens no matter what from the negative pulse from the remote starter, accept a slight voltage drop which isnt enough to pull the contact. 

Believe me, I have the correct wiring.  But the internal diode interests me.  The trunk release pulse wire is like 150ma.  I THOUGHT I had the right relay, I got it from Parts Express a 12VDC Automotive Relay SPDT 30A.

The problem I have is this.  I wire it according to what is stated above.  I test the RED / white trunk relay wire from the unit, and it reads ~200MA and up to 500ma.  When I test terminal 85 before attatching the RED / white wire, it reads 12.5v.  After attatching the RED / white wire to terminal 85 it reads about 11 volts. 

I thought that a difference in voltage between terminal 85 and 86 was supposed to close terminal 87 and allow voltage to pass through terminal 30 to the trunk.  But nothing happens.  Only a complete ground to the chasis will activate the relay.  This is the relay I bought: http://www.partsexpress.com/pe/showprod.cfm?&DID=7&CAtid=47&ObjectGroup_ID=31

Is this relay the right type? I thought it was...let me know ok? thanks!

How long are you holding the trunk release button down for. Same thing happened to me awhile back. The Button needed to be press for about 5 sec's then the release worked. Also are you sure you dont need to isolate the wire from the switch?

I set the computer to keep the pulse going until I turned the ignition on so that the negative signal was constant (for testing purposes).  But yes before I did that I had to hold the release button down for like 3 seconds for the remote to activate the signal. 

Im not sure what isolating the wire from the switch woud do...the switch is just a push-button that connects the constant 12v to the wire that goes out to the trunk...so when the switch is not being pressed it pretty much is isolated.

I just dont understand how I can be reading 11 volts on terminal 85, and 12.5 volts on 86, and yet the relay contacts dont move.  I guess I will see if I have another wire I can use to activate the relay....
