I'll give you some cliff notes and I really think we shoulf have a JDM vs USDM Headlight FAQ...
-It is not a straight wiring/plug and play. Cutting and splicing is required. It is actually pretty easy none the less.
-Decide what you want the blinker to do before doing the turn signal wiring. (You can have it as a turn signal only, turn signal and running light, or just as a running light)
-Bulbs for the High and Low beams have to be 9005 so you have to modify the plugs for the low beams.
Low/Hi Beam=9005 FOR SURE.
I haz JDM lamps. they fit a bit snugg but they fit.If ur car is a USDM model (aka GS300) the plug for your corner lights (blinkers) has 3 wires; this means the following:
-1 ground
-1 turnsignal
-1 running light
In the USDM cars, the corner light doubles as blinker and running light.
In the JDM car, the running light and the turn signal are separate. Corner light only acts as a blinker, runninglight is the middle 'cat iris' piece in the headlamp assy.
What you get when you switch from USDM to JDM are 3 options:
To make your corner light still work as a blinker/running light (stock USDM):
-Splice the running light wire and ground wire from the USDM corner light plug into the JDM runing light plug.
Result: when you turn your lights on, the orange corner as well as the JDM runing light will come on. When you turn your blinkers, only the orange corenr light blinks. My personal fav setup. If you do this setup, get a 2 colored 1157 LED where the running light is white and the alternate light is amber. I guarrantee you that if you have cleared the amber pieces from the headlamp, you WON'T BE DISSAPOINTED!

To make the corner light only work as a blinker light:
In the USDM plug, identify which wire is the power for the running light and which one is for the blinker. Once the wires have been ID'd you have 2 options: Use the corner JDM plug (2 wire connector) or, leaving a lot of slack, cut the running light wire off of the USDM plug.
Result: the corner light will only come on when your turn signal comes on, running light will be the 'cat iris' only.
Have the corner light work as a running light only:
I do not recommend this setup since you lose your front signals and it might be illegal in some states.
Basically all you do is cut the wire for the blinker and wire the JDM running light to the other 2 active wires.
Result: The corner light doesn't blink and it just acts as a running light.
Hope this doesn't confuse you!
