I bought that JDMToys DRL kit but never got it to work aside from the parking lights replacement.
The solution was easy. Open up the relay box cut the DRL light wires attach them to a spade connector and put it in the empty relay socket that is in that box.
DRL will come on when you turn on the car with that mod. Easy and takes less then 20 mins of your time. All you need is some basic tools, electrical tape. I did it in the parking lot of a hotel I was staying at lol.
