I copied this from another forum that should not be spoken about
My brother in law and I installed the GReddy TT (black of course) last night in the Speed3, and I wanted to make sure anyone else out there had an Idiots Guide to the install. (Sorry no pics, I’m working on that!)
First, read through this entirely before ripping the car apart!)
Let's start with the box. We all know how to read Japanese, right? So, the next step is to log onto GReddy’s website, and they have the English version to download.
You’ll have the timer, an extension harness, double sided sticky and a couple zip ties. (Depending on where the timer will be installed will determine if you will use the harness extension-for install on the top of steering column, you will NOT need the extension!)
Disconnect the negative terminal.
On to the car (beautiful car that they are).
Disconnect the negative terminal.
Push the seat back, tilt the column up and pull out as far as she will go.
On the bottom side of the column, you will find 3 Phillips screws securing the shroud (2 in front, one tucked in the back- you will need an extension, and some patience removing the back screw!)
“Finagle” the shroud off the column (I removed completely) you will need to unplug the little red light from the shroud in order to drop it!
Remove the top plastic shroud buy pushing the 4 rubber grommets out of the shroud, and pull out of the way. (Leave the rubber tucked in the dash-it is a PAIN to reinstall this piece!)
You’re now looking at a ton of wires. This is easy, I promise.
The SPECIFIC wires we are looking for (on the Speed3) all come off of the left (Drivers side) of the column. There is a gray connector that attaches the harness to the column. Pull down on the gray bar, and wiggle out (its okay to use some force the wires are in the connector pretty well). This is where we are going to look for our 3 wires (the timer has 4-The black wire is for a ground only!)
Begin by cutting the harness off the unit (NOTE: leave the harness on if you are choosing to locate the timer in an area that the short wires will not reach! You will need to plug the extension in, and then cut the harness off the end of this, NOT the Timer Unit!). Next strip 1/4'”-1/2” of wire from the Black, Red, Blue and Green wires on the Timer unit (or harness extension). (set aside for now)
In the wiring harness we removed, we are going to need the BLACK AND RED (continuous 12V supply), PINK AND YELLOW (ignition/ON), and GREEN AND YELLOW (2nd ignition).
The pattern that we will need to solder wires is this:
Car: Unit:
Green / Yellow Blue
Pink / Yellow Green
Blk / Red Red
Bolt Black (ground)
Don’t make finding these wires harder then it is, they staring right at you (I looked, and looked…they’re right there)
Once the 3 wires have been located, you need to make a choice as to how you will attach the timer wires (i.e.-solder, butt connector, ect.)
If soldering, strip ” of wire from the middle back (towards the engine) of the selected wire (do not cut the wire through, only strip, and remove the vinyl insulation)
Once the wires have been securely attached to the harness (your own opinion will know how well they are attached), be sure to cover the solder with splicing tape, or a good 3+ rolls (not the whole roll…) of electrical tape. If using butt connectors, shrink tube is the best bet here (you need to remember to push this on prior to solder!)
The unit is wired. That’s it. Simple. We have now told the cars computer that there will be a key in the ignition, turned to the ON position, even after we remove the key. (Kind of like the remote starter systems for us peeps in the Deep North).
There is a test run through that GReddy has you perform prior to putting the column back together (I will not add this here it is on the website, as well as in Japanese included with the Timer).
Once you are confident that the unit is performing correctly, and you feel secure in your solder or butt (connector), let’s start to put the column back together.
NOTE- I chose to locate the unit on the top of the column, just off center (my choice, no comments please) so the put-together will reflect this!
Begin by “finagling” the lower column shroud back over the tilt handle, and under the lower dash shroud (let hang). I chose to snip the #2 grommet out (to feed the wires through) as well as the corresponding plastic plug on the top shroud. (For a cleaner look, you could choose to drill the correct diameter hole through the plastic and grommet, and prior to soldering, feed these two pieces over the wires.)
Once the correct cutting has been done, begin by feeding the remaining 3 grommets back into their respective holes. Once you have attached the top column shroud to the rubber dash piece, plug the light back in, and snap the lower shroud to the upper shroud. (Your column should now resemble stock (with a kick ass timer hanging on the top).
Proceed to reinstall the 3 Phillips screws we removed at the beginning.
Apply the sticky tape (supplied with Timer) to the TIMER first, then position and press firmly across the top to ensure a tight fit. (NOTE: Depending on dash products used to clean or care for your car, make sure the adhesion point is clean of any Armor All type products!)
Surprise! You’ve now completed the install portion of this guide.
The GReddy manual will have a couple test runs that they would like for you to perform prior to taking the car on public streets, please be safe, and make sure you are comfortable in the operation of the Timer prior to driving.
Thanks to all the guys I called (you know who you are) and all the members of the forum for their input.
Michael
PS
There are 3 other wires connected to the timer unit. The GRAY wire is not used in the USA, period. The pair of PURPLE and BROWN wires are the speed sensor wires, and the E-brake sensor wire (Purple=Speed, Brown= E brake). Simply clipping the harness, strip the BROWN E-brake wire and ground this with the black wire (to "correctly" install the ebrake feature, you will need to ID this wire (I didn't, and I dont think I would know where to start).
