interior lights wiring harness adapter

[maverickz]

Hi, just would like share the wiring adaptor that I have purchased.
Basically it's a simple male and female connector with few wires, it added 2 additional wires to output 12v DC.
Label shows it called "Wiring harness adapter for MG"
This should give 12v DC power as soon as you unlock the car and power off once locked.

the DC + is pin3
the DC - is pin4
the connectors are from TE:
here are the part numbers for the housings that you need
1703874-1
936289-2
just check on TE's website for the crimps that you need as per the wires size that you have got.
the rest is like for like wiring and add 2 wires for pin3 and pin4 to get 12V power for light at rear or dashcamera.

here is the connector on the back of the interior lights.
Thansk to @Oberoy , I borrow the photo from his post.

Improving interior lighting in MG4

Eek. I've got a problem. When pushing the new LED into the socket it fell through the plastic molding. I've tried for 15 minutes poking it back into place but the clips on the side are preventing it getting back to its original Position. I think I need to remove the plastic panel which holds...

What are you using this adaptor for?

Power my dash camera.
you can also use it to supply power for interior lights at rear if you are going to add lights.

I do wonder about putting a panel-mounting USB socket for a dashcam in that blanked off section opposite the SOS button?

Bear in mind that this is 12V power, so you'd need a 12V/5V converter for a USB socket.

This looks really interesting and would be great to be able to build one of these adapters as it would make powering the dash cam so much simpler.

This looks like it might be a way to build the cable but the lead time is looong - 1.71￡ |1-20 Sets 4pin 0.6 Mm Male Female Auto Electrical Plug Trunk License Plate Light Connector 1703874-1 1719684-1 - Connectors - AliExpress

I wondered about the size of that, but there's space in the roof lining above the cluster assembly for it to fit.

I paid about £7(without delivery charges), for the adaptor and including the 12v to 5v converter.

there are plenty space there, the converter unit itself is vert small and flat.

That looks like a much neater install compared to having to run fuse taps from the fuse box, nicely done. I may look to try something similar myself.

Where did you source your power box? Thanks

That’s mentioned on the last page of this thread…

Dashcam install

Had my dashcams professionally reinstalled today. For anyone interested they were able to use empty live and switched live slots in the fuse box rather than tapping onto existing fuses. He installed a battery monitor to ensure voltage doesn't drop too low. I will try and get the pictures and...

…it’s from Taobao, a Chinese supplier as far as I’m aware. Macerickz described it as the original Ali Express

just the 12v-5v adaptor? or including the wiring adaptor?
you can easily buy the 12v-5v adaptor on ebay or amazon.
I have 2 spares right now actually, I can sale them.

the wiring adaptor is from Taobao like Diggsy said, you can make your own adaptor with the right connectors or you can take power from the original interior lights' wires via splice connectors.

I have bought 2 sets wiring adaptor from Taobao, I should receive the second one in a month time. I'll post the second for sale in here as I only need 1 set.

 

[dawson2099]

Mainly the wiring adapter - as you say the connector is more easily adapted. Give me a shout when the 2nd arrives and I'll buy it from you.

do you have a url to the page where to buy this adapter aka splice kit ? I tried to find with no succes?

 

[misiekz]

I looked at this website but it is all in Chinese and even Google doesn't translate properly so got stuck. Get a few more if you know what you are doing and I bet people here will buy it of you.

I have a spare one now.
Let me see whether I can bring more to the UK.

 

[misiekz]

If you want to sell the spare one I will have it unless you have somebody else already lined up to get it from you.
Thanks
