    Let me preface all this with I'm no electrician or electrical engineer.
    Just a guy with a volt meter and way too much time on my hands.

    With that said, here goes my first attempt at a DIY.


    First thing I did, that will spare everyone else time, is buy both harnesses
    and do a pin for pin comparison. See below.

    Although you guys might want to have a donor Si harness around so you don't kill your stock one.

    With that in hand I went after labeling every connection to figure out what was what.
    Did this by matching up connectors that would be the same on both cars and working
    backwards from there. See difference below

    Those are the main connections.
    There are other difference, but those are coming up.

    Here are the harnesses side by side and the connections that need to be addressed

    Highlighted section is where all the magic happens.
    The upper harness is the Si, notice the extra white connection.

    As many people speculated on how to do this, splicing into the main line, that's exactly what Honda does.
    Here is their splice point. It's about 12 inches from the main connection.

    [​IMG]
    I cut the wires at the main connector and just below the crimped connection.

    I also traced the connector's ground back to the main bundle, and removed it, and cut the extra ground wire off of it.
    To undo the bundle, twist the top eyelet to the left and it will pop loose. Repeat until you get to the one that you need
    access to. Not sure if it's the same order on all harnesses. Use your own judgment.

    [​IMG]
    Here is the needed connection removed from the rest of the harness.


    Next up is soldering stripping a small section of the bright green wire (pin 7) on the Si harness.
    I chose to put my connection closer to the main connection so I had plenty of room to run the wires back up to the end point. (Yes I forgot to take a photo of this step. I will try to do another one this week and post it)

    Updated Hybrid Harness with 3rd brake light harness added.

    Completed harness. Nice and clean, unless you look closely, but needs to do that. Honestly :confused:

    After that just follow College Hill Honda's install video and you are good.

    Finished product

    If I have a trunk made for the SI without the spoiler holes and everything will these be direct plug and play for me? a spoilerless SI with the lights? or will I need to do the same thing to get it to work? (my trunk is a CF trunk) and i do not want a 3rd brake light.

    If you are not running the 3rd brake light, then you can just follow the College Hills Honda video.
    The main connection is the same.

    Does it illuminate and look the same at night as our non-hybrid taillights? Would love to see night shots if they do.

    Thanks AP!!!

    As for what they look like at night, the last installed photo is parking lights only.
    They do look different, they don't wrap around up on top. Kinda hard to describe.
    I'll try to get some night shots once this snow stops Jersey. UGH

    You sir are correct.
    I've got a before pic around somewhere.
    I'll post up a side by side.

    Here's a side-by-side
    side_by_side.jpg

    As you can see in the stock housings, the lights wrap up and over the "silver trim" piece on the trunk.
    The hybrid ones stop at this trim piece, but with light pipes it kinda makes sence.

    The top portion of the hybrid ones is not exactly a reflector, but not just dead space either.
    It's a smoked plastic with chrome highlights under clear plastic. More of the chrome highlights
    face the rear, so I guess it could be considered a reflector. :confused:
    I think you can see what I'm talking about in this shot.

    I'm wondering this too - do the hybrid taillights perform and better/worse (brighter, dimmer, anything)?

    I think they are a touch brighter all the way around. Especially when viewed from another car.
    If you are looking at them from standing height and very close to them, they look dimmer.
    But again from the position of another drive they are just as if not brighter than stock.
    They also illuminate faster, although that is subjective....
    I think they look great at dusk, the light pipes light up real well and are just distinctive.
