OK I have added a Gear Position Indicator behind the tachometer and this is how I did it.
I know there were some people that were afraid to open up the speedometer thinking they might do damage to it.
I do not consider myself to be an electronic whiz by any means - so if I can do it, most of you could do it too.
Yes there is a little prep work and the nose fairing needs to be removed to get the speedometer gauges off the bike.
Once the nose fairing is off there are 2 screws holding it down and a couple of pointed studs that are held in place by rubber grommets that just pull out.
Remove the plug and your all set.
You will need a Phillips screwdriver, some wire cutters, needle nose pliers a soldering iron and solder and desoldering braided wire or a desoldering bulb.
Electrical tape and a few wire connectors. Nothing too major - many will already have most if not all of these things on hand.
So here we go.
Start by removing the seven screws on the back of the speedometer - then remove the back.
Once the back is off this is what you will see.
These 4 clips need to be bent straight up.
I used small needle nosed pliers to do this and it worked fine.
Then using a soldering iron I heated the 4 pins so as to remove the solder.
I had to go over them a couple of times but it was no big deal and the solder came up easy.
There are three screws that need to be removed and when I did, the tech was easy to gently pull away from the board.
So this is what it looks like with the tech off the board.
This is what the back of the tech looks like.
The LED's fit over 2 of the attachment points where the screws were removed just prior to the tech coming off the board.
Before you reassemble everything this dust cover needs to be removed.
Then this hole needs to be made larger for the wires to fit through.
I used a step drill bit and opened up the hole 2 steps, which is about right for the connectors and wire to go through.
The wires need to be routed gently around the back of the tech and around LED"S so as not to bent any of them out of position.
Then the wires are pulled through the back cover.
This plug need to be wired up after the wires are pulled through the back cover.
Here is the plug all wired up.
And here is the Speedometer ready to go back on the bike. See that wasn't too hard of a job to do.
I might have preferred to have wired the plug up after I had mounted the speedometer back on the bike.
As there is a hole that I would more then likely have used. If any of you do this Mod then you might want to do this
He you can see that I zipped tied the cable in place - so I'm OK with it this way I guess.
Then instruction said to use the red wire from the ECU on the smaller of the two plugs.
I looked at a wiring diagram and decided to find where that red wire went as the wires at the ECU are bunched together pretty tightly and
harder to get at to get a splice. I found this wire for 5V of power and it looked a lot easier to get to.
So I spliced into it for my power.
Don't know why Suzuki never added this feature to the Gen I bikes as there is a Gear Position Sensor already on each bike.
Basically just unplug that connector and plug in the wires from the harness and your good to go.
Here is a quick image of the LED showing 1st gear.
And here is one of second gear with the engine running. I assume that when the bike is outside (it's in the house now) there will be no glow around the other numbers.
Especially because I usually ride this bike more during the day then I do at night - but that's just me. I have another bike if I want to ride at night.
Many thanks to Echobase. Because I'm colorblind I did need to send him an image so he could confirm that I had the right wires in the right
place while putting the pins in the plug. His instructions were/are even more detailed then what I'm showing here. So I felt this was an easy mod to do and
maybe one of the best that I have done so far. I really like the clean install of this vs the box that many have on there bikes. No one would ever
know this mod was on my bike unless they rode it. So no one is going to steal something they cant see.
I would do this mod again and I hope that I have relieved any fears about doing this to anyone that doesn't have but would like to have a GPI behind the tech.
Hopefully never again will I look for 7th gear.
Or try to take off from a stop in second.
I'm sure I'm probably the only one that has ever done that, right?
Now I'm really ready for Spring as I really want to try this out on the road.
I guess there is still time for anyone wanting to do this.
