DIY: G37 Sedan Illuminated Door Sill Installation
With the T-harness? Are you referring to where on side goes to the passenger side sill and the other splits off to be run from one side to the other for the driver sill? I bought a kit from iCrap so if you'll elaborate some more I can probably help.

No harness
Correct me if I’m wrong but I don’t believe it is a t harness- all 2nd gen g’s just had a harness for the illuminated kick plates. For those sold without them they are just a plug with nothing going into it?
If installing without a harness - just tap the two wires - if you need to know which wires then look up the diy section as it is explained with pictures

Yeah I think you're right Str8Gtime but I'm not sure if there's an extra plug or if it's just extra wires within the existing plug. If that makes sense.
But yeah tap the two wires mentioned in these threads and you'll be good.
FWIW I tried searching for the factory harness with no luck. You'd have to find a wrecked G with factory illuminated sills and pull the harness from it. Too much trouble and not needed.

Establishing Connectivity
Remove the shielding on the harness to expose the wires
Switch to the illuminated sill harness - take a pair of wire cutters and remove the plug on the end of the harness. Ensure you are cutting the plug off IN FRONT of the inline fuse, and NOT either of the plugs that accept sills themselves.
Use a pair of t-tap wire connectors to connect the RED and WHITE wires from the sill harness to the BCM harness.
WHITE (SILL HARNESS) connects to > SKY BLUE (BCM HARNESS)
RED (SILL HARNESS) connects to > MINT GREEN (BCM HARNESS)
Looks like white wire from the kick plate goes to the plug pictured above and the sky blue wire
Red -> mint green from the same plug
I tapped this plug to install my footwell lighting. Pretty sure it is just the interior light / dome light circuit but if you are cautious like i was - maybe just buy an inline fuse just in case?

I already have illuminated kick plates but they need replacing. They don’t fully light up. Only the middle of the Infiniti lights up, not the full word. It looks really bad but since I already have the illuminated kick plates, if I could get some used ones that worked good, would it just be plug and play?
