how to wire the trunk pop /w compustar

Hi I got an question i had compustar 2W8000FMR installed on my 2002 Nissan sentra specV with dealer. However i only have door lock and unlock installed and now i am trying to install the trunk pop myself i did some research this is the 2000 -2006 Nissan Sentra Wiring Diagram http://www.commandocaralarms.com/wiring/2000-2006/Nissan/Sentra/1268.html and this is the manual come with my compustar What i found out is the dealer connect the the Blue from CN4 at compustar unit to PURPLE / red and Blue/Bk to grey (unlock and lock) which match the wiring diagram however it not work when i try to connect the Voilet/Wh from CN4 to Red(-) the trunk release All these 3(lock, unlock, trunk) wires goes to my SECU and all these function i have with my orginial remote so all did is tap the trunk wire with PURPLE / wh but not work i have double check my trunk latch and very sure it's red Anyone have any idea why? did i make any mistake or i miss some steps? anything to do with the Aux2 on CN2 of my compustar unit? very apperciate if anyone can help me

With many cars the doors have to be unlocked for the trunk release to work also if I remember correctly nissans need a very strong ground signal to get the trunk to open use a relay to do this"Computer games don't affect kids, I mean if Pac Man affected us as kids, we'd

I believe you are refering to is a high-current (ie. direct-wired) load. The PINK/BLACK(Trunk Release) wire, in pin 12 at the SECU, would be an example of this. It requires a relay to control the load, as it is the direct GROUND wire, from the solenoid.

you mean the pink/black is the strong ground for trunk release? do i need connect my compustar unit to this wire for trunk release? if so which ping in my compustar unit thank for reply

Violet/white at CN4 to relay 85, 12v+ at 1amp fused to relay 86, good ground via a chassis bolt to 87 and 30 to trunk release wire pink/black.

No you buy a standard 4 or 5 pin relay, if you buy the 5 pin, 87a isn't used.

ok i think it's no in compustar unit you said Violet/white at CN4 to relay 85 is 85 |TRNK/HTCH RELEASE|red in my secu? (that's where i tap the wire first time)but not work maybe i didnt do following 12v+ at 1amp fused to relay 86, and good ground via a chassis bolt to 87 and 30 to trunk release wire pink/black i know where is the pink black in my secu but dunno about the relay 87 and 30 kinda confused here please help me if you can thanks |       ITEM      |     WIRE COLOR     |POL|       WIRE LOCATION        | |              12V|WHITE/ red           |+ |ignition harness            | |          STARTER|BLACK/ white        |+ |ignition harness            | |   SECOND STARTER|BLACK / YELLOW        |+ |ignition harness            | |        IGNITION|BLACK/ red           |+ |ignition harness            | |        ACCESSORY|white|+ |ignition harness            | | SECOND ACCESSORY|WHITE/ blue          |+ |ignition harness            | |       POWER LOCK|gray |- |Time Control Unit or SECU *1| |     POWER UNLOCK|PURPLE / red          |- |Time Control Unit or SECU *1| |       LOCK MOTOR|RED / black           |   |pin 15 at SECU *1           | |     UNLOCK MOTOR|blue/red            |   |pin 13 at SECU *1           | |    DISARM DEFEAT|WHITE/ red           |   |pin 14 at SECU *1           | | PARKING LIGHTS +|wht/red or RED / blu |   |headlight switch or DKP     | | PARKING LIGHTS -|org/blk   (hazards) |   |pin 7 at SECU *1            | |       HEADLIGHTS|RED / yel(L), purple(R|+ |headlight switch            | |     DOOR TRIGGER|*2   |- |*2           | | DOME SUPERVISION|use door trigger    |   |             | | TRUNK/HATCH PIN|RED / black *3        |- |trunk light or SECU *1      | |        HOOD PIN|pink/black          |- |hood switch or SECU *1      | |TRNK/HTCH RELEASE|red |- |release switch *4           |<--------------85?? | FCTRY ALARM ARM|lt.
