Your making it harder than it is.I just did this on my kouki Bumper... but My Project I did something diff.
The front bumper Turn signal harness has 3 wires ; 1 blk 1 red and 1 green.Green wire is what makes the light Blink. so w/ that your working on -you want it to blink????...It should just light up w/ 1 click of the Headlight stalk would be "factory".Bottom lights would be blinker but You'll need to use the green wires and maybe get a dual Filament bulb.

Use the Bumper sidemarker light harness and Splice into it (run wires)and the 2 wires will allow that to do So ^ once you run them to the Square position Lights w/ the harness' and Bulb sockets.

The Blinker Bottom lights is where it get s tricky.that light is not supposed to be on -- ONLY when the blinker is on.....now thats how it is in Japan...you can however do what you want for them.....You have to use the OEM front bumper harness where the old Chuki Lights were and use the Green wire from the harness and 1 other one..can't remeber which one.But thats not what your working on in question.

Now...The front bumper/fender sidemarker I made Turn on and light up as well as blink w/ the front blinker lights.That was hard as hell.Your own your own there cuz I couldn't walk youn though that,Otherwise those sidemarker lights will only light up or NOT @ all.Very dangerous when trying to change lanes.
