S-CROSS DIY - Foot Well Lights
The top end alpha version of S-Cross is mostly feature loaded, but yet there are a few simple nicecities that are easily doable. The interior cabin light is poor and an upgrade to LEDs is recommended since they are a straight fit. This can improve the overall lighting inside the car. One of the areas that is not well lit is the back side foot wells. The ones in the front use a single LED and not powerful enough, especially if you have a poor eyesight.
I had got LED scuff plates as part of accessories from Nexa at the time of delivery of my S-Cross, but as many know, they are purely cosmetic.
My son does drop things occasionally during trips and it is sometimes tricky to find something in the rear floor area at nights. Given that there was a power source close by, I decided to complete a DIY to install LED foot well lamps at the rear. There are many other threads on how to install LED foot well lights. Well known are Gannu_1 and a4anurag's threads. This is well, yet another foot well lighting thread but what is different in this case is the approach I used to tap power from the scuff plate lights.
The scuff plates connections use simple molex connectors and therefore the easiest way to tap power was, to create a power splitter by using equivalent molex connectors. Further, they also follow the theatre dimming effect when turning off or on as followed by the scuff plate lights. The line is also secured with a 3 Amp fuse and therefore there is no need for an additional fuse as long as you are not overloading the line by adding too many LEDs
Ingredients- Male/Female molex connectors and terminals (Source S. P. Road, Bangalore. Cost INR 10 per piece)
- Wires 24-26 AWG will do. (Source S. P. Road, Bangalore. Cost INR 6 per meter)
- LED lights - (Source eBay. Cost 200 per lot of 10)
- Zip Ties (Source S. P. Road, Bangalore. Cost INR 30 per packet)
- Insulation Tapes (Source S. P. Road, Bangalore. Cost INR 10 per roll)
- Crimping Tool (Source S. P. Road, Bangalore. Cost INR 800 per piece)
Procedure - Create two splitter connections using molex connectors and terminals.
- Connect the LED's to the male connectors.
- Remove the Scuff plates
- Plug and Test
- Replace the Scuff plates and attach LED lights into the foot well using double sided tapes or Zip ties.
Time Required to Complete this install: 1 hour or less with all equipments ready to go.
Crimping
It's extremely easy to use crimping tools to crimp terminals to the wires over soldering. The connections are flexible and they are pretty robust. Investing in a crimping tool is highly recommended. The brands available in India are alright but not great in quality. There are very cheap and better options available from AliExpress though, some even come with detachable dies so that it becomes multi purpose.
Let the pictures do the talking now.
Required Materials
Terminals. These will lock themselves into place once you insert them into the molex connector
Terminals - Crimped (The insulation crimping was not good enough due to quality of the crimping tool). Also, post crimping, the terminals could bend a bit due to the stress applied, in which case you will have to straighten out the terminal to ensure a smooth connection. Ensure you hold the center part of the terminal when straightening it out since they are not very strong
Splitter Created using terminals and molex connectors. The top two host the male connectors and the bottom hosts the female connector that plugs into the male connector for the scuff plates power source.
Using the crimping tool. It has a holder so that you can hold the terminal,push in the wire and then push crimp in one shot
See the small level near the handle? That is used to release the hold lock
Two - One for each side NOTE: LEDs are polarity sensitive and therefore when inserting the terminal into connectors, ensure the polarity will be correct when connected.
Splitter connected to the front side scuff plate connectors
Testing
LED foot lights attached using double sided tape under front seats. You can attach it anywhere you like
Wire exiting from the scuff plates connection, hardly noticeable
Wire routing - Ensure sufficient flexibility so that when seats are moved all the way front or back, the wires don't strain
