Accord Trunk Popper plz help! - Honda Prelude Forum

sexysilverluder · 05-07-2008, 01:09 PM

Everyday I use my key to open my trunk and I would much rather use the little remote i have, it has 4 buttons, one of which is AUX

I have been searching the site for information on the accord trunk popper and I have found a cuple things that i need clarification on, please!

Apparently there are two accord trunk poppers, one with 1 wire, and 1 with 5 wires... i want the one with 1 single wire for simplicity of course, so can someone tell me which accord year this one is from/ part#/ link to where i can buy it.

next, i guess i have to hook this one wire up to a active source of electricity... where and how do i do this please...

and most importantly once its all hooked up, how do i make my AUX button pop my trunk???

Your help is greatly appreciated!

there's a writeup somewhere. That's how I found out how to do this.

You'll have to provide the popper with a ground signal. You'll take the appropriate output wire from your keyless entry unit, wire it up to activate a relay that will provide the output terminal (30) with a ground signal. Hook up the trunk popper to the output terminal (30). You'll need to be familiar with a relay to do this. It's not hard and you can find the educational resources and diagrams by searching online.

Here's the necessary info though:
terminal 85 - aux channel output wire from keyless entry (must be negative trigger)
terminal 86 - +12v constant
terminal 87 - Grnd
terminal 87a - not used
terminal 30 - output to trunk popper

The trunk popper only has 1 power wire. The trunk popper is grounded through it's own body when bolted into the trunk. The trunk popper needs a momentary +12V pulse.

Your alarm's aux output is usually a ground signal. The ground signal activates the relay, the realy sends +12V to the trunk popper.

BBYlude almost has it correct,

terminal 87 should be +12V Constant, NOT ground

this completes the circuit and sends power to the trunk popper.

i would really like to do this to my ride, i wonder if it will work with the Honda Factory alarm system thob

sexysilverluder · 05-07-2008, 08:45 PM

thanks but where do i wire it to, is there a 12v momentary pulse in the trunk, like where in the car do i route the wire? im a noob to this...

and say now that its wired to the proper 12v momentary pulse, how do i make it so when i press my aux button the trunk pops open?? again... this is completly foreign to me

thanks for your help so far though

ps. does anyone know which poper is the one i want, i want the one wire popper not the 5 wire one, what year honda accord does it come from? or part #

BBYlude · 05-07-2008, 08:46 PM

did you try to look for the writeup? It is all explained in the writeup. As well, if this is all completely foreign to you, I'd let a car audio installer do this. It's easy to mount the new trunk latch, so if you brought it to a shop already mounted, they'd be able to do it no problem.

sexysilverluder · 05-07-2008, 08:48 PM

ive searched and read a bunch of stuff if u could link me to this write up that would be great thanks

BBYlude · 05-07-2008, 09:00 PM

Well here's some part numbers for the accord trunk popper that I found during my search.

Honda Accord Accessories - Audio and Electronic Accessories - Genuine Factory Honda Accessories, made by Honda for your Honda. go down to where it says 'trunk popper'. It's on back-order, but you should be able to get a part number for it and use that as a search term in a search engine.

Or this: FS: Accord Trunk Popper

Or: Accord Trunk Popper - 2 door or 4 door

And it took 10 minutes of searching, but I found it: Accord trunk popper into Prelude--how-to

all it takes is the right search terms and a little patience...

I'm not sure if the Prelude alarm has an AUX function. I use a Viper/Clifford and have it set to the AUX. Just hold it and "pop".

in two years of installing remote starts and keyless entry systems into cars, I've never seen/heard of a factory keyless system equipped with an unassigned 'aux' output. I'm gonna have to say no on this one.

liquidxnitez · 05-07-2008, 10:42 PM

The prelude key fob does not have an AUX button. So, no you can't use the factory system.

Step 1
Find out what alarm model you have

Step 2
Find the wiring diagram for your alarm

Step 3
Find your alarm brain, find auxilary wire

Step 4
Get a relay

Step 5
Connect auxilary wire to pin 85 on relay

Step 6
Connect pin 86 and 30 to a +12v Constant

Step 7
Run a long wire from the relay to the trunk

Step 8
Connect the longass wire to the trunk popper, and the other end to pin 87

Step 9
Cut a hole in the box

Step 10
Put your junk in that box

Step 11
And make her open the box

And that's the way you do it

When you press your aux button, the alarm brain will send a ground pulse to the auxilary wire, which will then activate the relay, which will send power to the trunk popper, which will open the trunk.

note: Dick in a box is optional

steps 9-10 make the process much more fun

Are you sure the trunk popper require a positive pulse? I seem to think it takes a ground, but I could easily be mistaken.

buy that, off an 01 accord, part # is at the top

You will need the relay if you have viper or clifford and the other brands made from their umbrella.

If you have a compustar, it is already a positive out so you do not need the relay.

Follow instructions on the HandA site and read here for more info:accord trunk popper - Preludepower.com

pretty sure, the trunk popper is grounded through the mounting bolts

where would the trunk popper get its power from otherwise????

The compustar's trunk popper is sometimes pre-wired to an relay that sends the positive pulse, however the activating wire is still a ground pulse.

(I say sometimes because it depends on what the original installer chose, it's defaulted to wire to the trunk popper but some people use that relay for the remote start or anti-grind)

harmonichonda01 · 05-08-2008, 03:47 PM

hmm didnt know that, but each compustar i've seen had positive wires out not a ground pulse even if with remote start and trunk pop

Maybe the relays were built into the brain in the older models? I installed about 40 of these with the CM3000 brain (2WSS-AS/2W900FM-AS). These all had an external relay that was prewired to brain. The positive output did in fact come from the relay, but the relay was still activated by a negative pulse which you needed to connect together (with a violet wire IIRC).

The reason the relay wasn't directly hooked up to the trunk pop wire in the first place, was because not all cars had a trunk popper

thanks everybody that was perfect
