Hello Friends,
Today I have received the Voltmeter + Thermometer (that is specifically designed for Honda City blank socket) and it took 18 days only.
Built quality of product is good but the letters printed on front face aren't perfect nor good quality ink is used, so they may wear off soon. Voltmeter fits perfectly into the blank socket hole and it gives a factory finish. First I have tested the meter by connecting directly to battery and it showed the voltage as well as temperature. Then I have continued installing the product without any issues. However, the voltage reading is slightly less (~0.2v) compared to my old voltmeter that plugs into power socket, even though the wiring is connected to the same fuse. To triple test, I have used multimeter and the reading of new voltmeter is 0.4v less. May be the calibration is not accurate and I don't think there is way to change it. Not a major issue for me, still I have sent message to the seller and lets see what he says.

Details)
Buyer Notes:
There are two models, big size for previous gen Honda City (2009-2013) and the small size for current gen city (2014-present). Take out the blank socket cap from your car and check dimensions before buying. You can also find different accessories that can be fitted into blank sockets. Such as, voltmeter + usb sockets, usb charging sockets, DRL switch and etc. However, I couldn't find blank cap for sockets so we have to keep the OEM caps safely.
Installation Instructions:
Note: Before proceeding, test the voltmeter by connecting to car battery or any 12v DC power and see if it shows correct readings.
Step 1. Soldering fuse tap and terminal lug
The voltmeter wires are open ended and you'll have to solder fuse tap to positive wire and terminal lug to the negative. This way the installation will be neat and can be reverted anytime.
I couldn't get high quality or thick wire lugs locally so I had to buy from Aliexpress. 50A copper wire lug
link.
Step 2. Removing driver side glove box, firewall panel and blank socket cap.
Honda City's fuse box is hidden behind driver side glove box.
To remove glove box, open it and pull the bottom part on both sides (upwards) and it will pop out. Take out the glove box and keep it aside.
Reinstalling is little difficult so watch how you remove it so that you can reverse the process easily when refitting.
Firewall panel which is above the pedals also need to removed so there will be more space to work on wiring.
The panel has two locks; right side there is a knob that needs to twisted to unlock and on left side there is a metal clip that can be released by slowing pulling the panel downwards.
Once the locks are opened, take the panel outside (Towards seat).
Blank socket cap has two notches but with a little push from behind, it should pop out. Incase its tight, press the notches with two fingers and push it outside.
Don't use pry tool and try to take out the cap from front, you might cause damage.
Sorry, forgot to take pictures after removing the cap.
Step 3. Voltmeter installation and Wiring
The voltmeter power cable has M/F wire connector, unplug it and keep the voltmeter aside until you route the wires.
Locate accessories fuse on the fuse box and remove it using fuse puller (Provided in the fuse box). Use the same fuse and install it in fuse tap. Install another fuse (10A or 15A) in the fuse tap for voltmeter.
Once done, put the fuse tap into accessories fuse holder location on the fuse box and make sure it is secure.
To connect negative wire, remove any nearby bolts, insert negative wire lug and fasten the bolt.
Now take out the wire connector from blank socket hole, reconnect the voltmeter and push it back into the hole alone wire. Make sure its not upside-down.
Tie the excess wires to nearby metal holes or rod but far from pedals, ABC cables, steering column.
Few months ago, I have installed dashcam hardwire via fuse tap and now I have used the same fuse tap for voltmeter connection.
Review of my dashcam and its installation is
here and hardwire installation is
here.
So now I can only show you wiring pictures of both the devices and it will help those who are doing similar setup.
Step 4. Testing the voltmeter and finishing the work.
Do a quick test of voltmeter and thermometer to see if it is showing correct readings.
Carefully refit the firewall panel and glove box by doing reverse procedure.
You have successfully installed the Voltmeter + Thermometer.
