I have a 06 lexus is350 (US), i have been research of a lot of post. someone said need to be extra wiring the led, someone said doesn't. Just want to make sure that do i need to be extra wiring for that extra led dot on usdm isf tail.

 

from my understanding the oem isf tail lights are plug n play. no extra wiring is needed.

 

These lights should come with a wiring harness. Then they are plug n play.

 

I got a email from nigel said "you need to order the harness or modify your existing harness to fit with the IS F tail light"

 

I ordered mine from Sewell and the harness was included. Either way you will need the wiring harness to install these if you do not want to cut and splice wires.

 

nigel probably doesn't sell the tail light with the harness. sewell does.

 

just installed mine 2weeks ago came with harness

 

I have a 2008 350. I bought a set of ISF tail lights (JDM) from ebay with no harness. the lights were plug n play no problem at all. All though I did have to trim the locking part of the tabs to get them to twist in to the locking position.

 

Nigel show on the website will come with harness for both usdm and jdm, but they send me a email that said need to be get it separate for usdm. jdm will come with the package. WTH NIGELLLL

 

The tail lights do not come with the harnesses, although Sewell may include them when they sell them.

Early 06's have different harnesses than late 06+, so that is likely the difference.
