2018 Trunk Release
 

Has anyone figured out whether its possible to retrofit the new 2018 cabin trunk release switch without the BCM module messing things up.

I notice Z1 Motorsports are stocking it which perhaps indicates it is possible.

It should only require putting the new switch in parallel with the existing switch. But I haven't looked at the wiring diagrams, so I could be wrong.

Wow $48 for a switch! Here are some cheaper ones that would work for less then $10, had them bookmarked for a future project.

Lol....buys expensive car and then complains about a $50 switch. Buy used ones off eBay for less.

Thanks for the info.:tiphat:

I bought this switch from Ebay. Cheapest I could find even with UK postage.

Sully,
I guess its a momentary switch and I use two of the four terminals?
Did you buy a connector for the switch or solder the wires?
Do you reckon the BCM will still be on the passenger side on a RHD car?

That's what I'd like to find....

That makes sense - I had overlooked the switch illumination.

I would really like to source a plug, I am hoping its a JST but I don't know the size. It might become clearer when the switch arrives.

When I was younger you could wander round car scrapyards removing parts you want but these days with health & safety in the UK you cannot do this any more in case a car falls on you.

mlsully and DeliriousClam - you both are awesome. Thanks for the info!

Question for those that have installed the trunk release using an OEM switch: the switch and pigtail I received has four wires coming from it (black, black/grey, blue, purple). Since mlsully said that it's a negative pulse switch, I'm assuming I'll be using the two black wires to complete the circuit (please correct me if I'm wrong). If that's the case, which of the remaining blue and purple wires would be used for illumination and what is the extra wire used for, if anything? My pigtail came from a Nissan Murano, if that matters.

You are doing great work, but sorry, I do not see the point of this mod. One still has to walk to the hatch and lift it. What difference does it make if you press a button inside or outside?

I am not trying to be negative or diminish your work in any way. Just trying to understand.

Maybe if I was explained what the advantage was, I would do this mod too.

I’ve used it many times where I pop my hatch when I pull up to a friend’s house for them to throw **** in the back of the car. It’s easier than trying to explain where the outside button is. Yes, for the most part it is redundant, but it’s a quick $20 mod and fill up the blank button slots.

Pretty much the same... and it gets rid of the last blank in my center console so that's just an extra plus.

No way anybody but me touches my car (other then dealership staff i guess).

Well then this probably isn't for you.

I want to do this but I don't have more button space in the middle of the seats!

can the trunk be opened when the motor is running?

For mine, the switch doesn't work unless the car is switched on.

I'm with ct on this one. You still need to get back there to open the hatch. Friend of mine tried to open/close the hatch from the spoiler and I said ah ah. "It is only I who can touch her there".

Even so --- I still repped when rep is due.

Keep a long pole to push open the hatch from the inside. Assuming you can't just accelerate to close the hatch (like you can with the passenger door), tie a string to the hatch so you can pull it closed from the inside as well :twocents:

Same here, everyone I know initially doesn't know where the external trunk release is situated so its easier for me to use an interior switch and saves me getting out of the car to open it for them.

2018+ Z's come with the switch anyway...

To conclude this thread today I ran the last wire to the BCM so everything works. It is indeed on the passenger side on a RHD - REP given to mlsully & DeleriousClam.:bowrofl:

I can now open the trunk whether the ignition is on or off.:driving:

I have a 2019 model. The trunk can only be opened if the doors are unlocked. Haven't tried opening the hatch while driving though haha, but since the doors autolock when you're up to speed, it will be disabled.

Trunk switch also works without turning the car on.

I’d like to do this mod too

So I like this mod for a few reasons but to answer the question of when it can be used click list pickup I don’t know how many times my wife has bought stuff and said go pick it up I have already paid for it, aka I can’t say i forgot to pick it up or I will get it another day, but try tell some dumb Kroger employe how to use the thing it just doesn’t work (no offense to any Kroger employees on here). And also it can be released when the car is running.

Did you get the switch to illuminate?

Yes, it turns on via the headlight switch along with the other cabin lighting.

I’m giving this install a try this weekend on my ‘13.

- do the blue and purple wires from your harness tap into the same blue and purple wires at the bcm?

- did you split into the wires at the bcm and run under the carpets to the center console? Or did you find a way to identify the wires to splice closer to the actual switch?

Any thoughts?

You only connect one wire to the gray wire in the BCM. The other wire goes to ground. For the illumination pair of wires, use a test light to see which wire goes positive from one the harness plugs under the cup holder that's normally used for the heated seats. Connect the positive wire there and the other to ground.

Following up on this

I purchased the interior trunk release switch from Z1
https://www.z1motorsports.com/switch...h-p-13339.html

It's part #25380-JF00A

Unfortunately, it does not come with the plug, or harness that actually is needed to splice the necessary wiring to it to make it work.

I looked on various parts databases and couldn't find anything resembling the necessary wiring harness

How have others who wired this up done it?

Going off of what OptionZero stated, other than finding use connectors from older Nissans that have the same plug, does anyone know where to buy a pigtail for the trunk release switch?

I bought mine from a 2013 Nissan Sentra... shouldn't cost more than $20-30 for the entire panel.

Did you buy it from a wreckers or new? Ideally I'm looking for new

New would most likely set you back in the $70+ range for the switch and most likely it won't include the pigtail. I bought mine from ebay and looked new when I got it.

Resurrecting this old thread. Thinking of pursuing this upgrade. Have everything on hand, including a switch from a Sentra, complete with a connector with the four pigtails attached. Wiring looks pretty straightforward. My only issue is accessing the so-called gray wire in the BCM in the passenger footwell that needs to be tapped into. The space is not only tight, but freeing up the gray wire to allow splicing with the wire that will run from the switch is hindered in part by the solid block of styrofoam that sits under the carpet at the front of the footwell. For those who have completed the work, how did you tap into the gray wire? I suspect you could use a standard wire tap, but I would prefer to solder the wires. Removing the styrofoam block to allow better access would work if it wasn't glued to the carpet. Anyway looking for advice from those in the know. Thanks in advance.

You really expect all of that for $84? (being sarcastic) :rolleyes:
Contact member nissantracker they've been selling center console switches and can probably point you in the direction of the harness and connector. :tiphat:
