Hello,I'm new here...looking for a wiring schedule to connect a koso to the original speedometer
Thanx
Mark, you might get a better response if you introduced yourself properly first with a bit of you biking history, age ETC. This is not facefuck.

Hi Mark, as already mentioned folk here like an introduction, it's just good manners and will get you a better response from most folk in the future.
What KOSO are you using?
95% of my KOSO I did just with a multimeter, it was pretty easy to work out what was what, folk on here helped out too.
The speedo I never did, I couldn't seem to get the bike and dash to talk to each other, not sure if they are compatible. My KOSO had its own speedo pick up, no glueing on magnets like some others, just a pick up head, I ran one wire down the brake line and mounted the sensor to count the disc brake bobbins.
I'd like to get it to work from the bikes existing feed but I'm not that smart with electrics. Maybe one day.

Oke,thanx...my name is Mark,did own a gsx1400 before,now i'm riding a gsx 1100 ef,i swapped the 1100 engine for a 1400 from the gsx i wrecked...
I wanna get rid of the big cauges and use a koso cauge,so i only need the wiring schedule from a gsx1400,,i know wich color the wires on the koso cauge are connecting to,but not wich colors are for what on the gsx1400 cauge.
Try to buy a schedule in the internet,but i don't use paypal,so thats why i got to this forum.
Thanx for the help

Hello,
Have a look in the downloads section, the Suzuki workshop manuals are there. They've got the wiring diagrams in.
https://gsx1400owners.org/forum/index.php?action=downloads;cat=6
There's a couple of supplements depending on the year of your bike, but I don't believe anything changed to the clocks.
Regarding the speedo feed, I've never checked but I wouldn't be surprised if it goes via the ECU & that's why the aftermarket gauges don't like it. It counts 4 triggers on the front sprocket, so at that point should give a simple counting signal the gauges would understand.
Handily the sensor is the same across loads of Suzukis, GSXRs etc so wouldn't be hard to get one to cut the plug off & connect directly to see if things work.

:cheers: thank you!!
Welcome to the forum Mark. :onya: How about posting a couple of pictures of your project, sounds interesting.

My KOSO lets you put in how many points it's counting, like 6 disc brake bobbins, so that could be set to 4 as you say.
I'm not sure if the signal reader on the 14 would be compatible though and talk to the KOSO clocks with a suitable signal, or if on the KOSO when it asks for the outer measurement of the tyre to calculate the distance traveled if that would be within range of the amount of sprocket turns to a specific distance.
I realised I wasn't that smart and used a front wheel sensor supplied. :confused1:

It's not something I've ever done, I was just thinking aloud there really. My assumption being the ECU takes the counting signal from the sensor to use for stuff & spits out a totally different signal type to feed the clocks.
Sounds like an interesting Frankenstein's Monster of a bike you have :)
