02 nissan maxima trunk release

I installed a compustar 600s into an 02 Nissan Maxima and the only part i cant get is the trunk release. I used the violet with white wire of the alarm which sends out a negative and the blue wire of the vehicle. The wire is right because when i give it ground the trunk opens but for some reason when i use the violet and white wire nothing happens. I also tried it with a relay and everytime i tried to do it nothing happens. I noticed that when i press the trunk release button on the remote the wire gets a signal but when i connect it to the relay and check to see i get nothing out that wire weird. Any advance would help and thanks in advance.Confidence is the key to any project!!

Wire as follows: Cut blue Violet/white from alarm to 85 12V+ constant 2amp fused to 86 Car side of blue to 87a Trunk side to 30 Good ground to 87 Diode 1N4004 across 85 and 86, band towards 86.

ok i was gonna try that what wasnt sure the car called for a relay thanks i will tryConfidence is the key to any project!!

The reason being that the blue wire need a higher current than any alarm-R/S trunk output can provide so your using the relay as a current amplifier.

well i added the relay but i never cut the blue wire i just added the relay to send just a ground signal but i will cut the wire so it can workConfidence is the key to any project!!

I wired it that way so the lead stays as original,that is like a 4 wire door lock.

That should be direct negative trigger dei's 200ma output on the trunk release suffices for that purpose.

Yes Darren but according to Directwire, it's high powered, more than any neg. aux will handle so it needs a relay.

I've seen an Autostart trunk release output fry on a 2002 Maxima trying to open the trunk. Use a relay to boost the signal and I also 5 wired the connection to isolate the switch from the motor.Jeff

I was about to have a go at you Jeff 'cause I already mentioned 87a and thought I said 5 wire but obviously I wrote 4 wire,,,FAIL. I think 5 wire is a horrible expression, can't we say "switching motor wires" or "relay interrupt".
