Ok everyone i have recently installed the JDM DCC. I have run into a few problems im hoping that someone will be able to help clarify. First problem of which is the lights when i turn on the daytime running lights and headlights the DCC unit goes very dim, and when i try to make them brighter with the dimmer nothing happens. i am not to sure what wires are for the lights on the dcc if anyone knows please let me know. Now the second problem is the outside ambient temperature sensor i also need to know the wire colors for it. I have all other sensors and motors hooked up unfortunately the outside temp sensor was cut. I am almost positive that the 6 pin JDM connector is where the sensor needs to plug in but i only need to splice 2 wires in, so just need to know what colors they are. Also need to know if its polarity sensitive. Thank for any help!! :chuckle:
Will also post up some pictures of the unit in a few days.

Ambient Temperature Sensor - (LG/Y +) - (LG -) - on the small white 7 pin plug.

I have not found a solution for the lights dimming. All suggestions online I could find were incorrect. Most said to use the exact same wire you have to cut and ground to get the unit to work so I gave up - for now.

Well i took the entire unit apart to trace the wires on the board for the light. From the DCC 16 pin plug it is the white/red stripe, and of course black wire unfortunately it does not dim. I am giving up on the dimming as well, not worth it. But thank you for the outside temp sensor wires i could not figure it out! :tisk:
