Does anyone have a wiring diagram or know the setup of the ignition coil loom? I've got the shifter itself and the controller, but i dont have the loom it plugs into! I'm capable of making a loom, but i dont know how it works, i can guess, based on the wiring diagram for the bikes ignition coils, but i cant work on guesswork! many thanks M
Probably easier to just buy a loom? By the time you've bought the right connectors as the loom sits between the coil pack and leads connectors of main loom
I understand that, everything is easier if you just buy it, but now i am also curious, and at nearly 70 quid for the loom, its cheaper for me to make one!
Am i right in saying that as the 5 connections that split in to the 4 injectors, 4 are 12v live and the earth is switched to give the spark signal? The quickshifter intercepts the earth and blocks it, essentially stopping any coils firing? There are 2 wires from the quickshifter control, i can only assume ( As i dont know better, yet) that it can only intercept the switched earth, i cant think of any other way it could work, unless all plugs fire at the same time, all the time, which i cant see.
I got the first part wrong, the joys of thinking about it for too long! The 12v feed is switched and the earth is constant, I knew that but wrote it wrong! So the earth is switched by the quick shifter, essentially stopping any coils from firing. Looking at the wiring diagram the seems to be a simpler way to wire this in. I just need to see the loom or a schematic of it!
Now all i need to know is if the orange wire is +ive or if the grey is! Its a simple circuit, and if im right, its a far far easier way of fitting than the way they suggest. i've confirmed the coils are permanent 12v live and switched earth, that was fairly straight forward, and the QS is fitted, i just need to know the polarity of the QS unit so i dont blow it up!! I'm fairly sure its diode protected, but i cant be sure!!! Does anyone know the answer please?
Dont worry!! Ive done it! no takin g the tank off, no removing the coil wiring!! taken about 40 mins of actual spannering!! I'm surprised that its made so complicated by HM, there is a much much simpler way to gain access to the coil wiring!! I'll go more in depth later on!
Ok, so, i managed it, i fitted the QS without removing the tank, without removing the airbox, and without the £50+vat wiring loom! Its quite simple really, after some research on the wiring diagram from the manual, it was clear that the coil loom is a sub loom, and is connected to the main loom on the right hand side of the frame, right where the Lambda sensor is and another couple of connectors. I went in there, instead of each coil. Now to be clear, my bike has nearly 30k on it, its not immaculate, its already had someone go happy with a set of snips under the fairing, so it didnt bother me too much to do the same! its a bit messy still, i wanted to see if it would work before making it all nice and tidy. Initially, after much research, i got the polarity wrong on the QS, so i made a reversing loom, which i also ballsed up and basically wired it in the same way as before!!! Once it was the right way round it all worked exactly as planned! i've been out and tested it, its great!! i'll add a couple of photos to the next post. In reality, it shouldnt be too difficult to get a pair of plugs the same, and make an extension to the loom that incorporates the splice off for the QS. It really only took me about 45 minutes to complete, albeit another couple of hours reading and making right what i had got wrong! hopefully this may be of interest to someone!
this is the plug in question, right hand side, under the mid fairing. the black and white wire is the 12v feed to the coil packs. Split that, connect the feed end to the orange wire on the QS, and the other end goes to the grey wire!!
Thanks, i'm quite happy with it! I just need to take it apart again and make it look a little more professional, one day! ha
I admire your ingenuity....however ....there must be a reason it's not supplied like that. I understand that they are making money on a superfluous (!?) additional loom, but they could just as easily offer a modded connector/connection as you have done. Have you been in touch with HM at all for any explanations on their loom and connectivity?
I was wondering why they would make it far more complicated than it needed to be, i spent a lot of time thinking about it before hacking and bashing. I cant think of any reason other than on some bikes there may be no option, and instead of design a whole new loom, they modify existing looms. There is no other reason. The quickshifter works fine, i have no trouble with it with it spliced in where it is, in an ideal world i would need both plugs to make a small sub loom that goes inbetween whats there, but to be honest, someones already been in there snipping and lecky taping stuff, so it doesnt look out of place!! I will tidy it up though, one day! I have emailed them, i was asking about it, but they werent very forthcoming with answers, so i gave up and winged it really. i'd imagine that all blades are the same, you could fit any HM quickshifter without the loom by splitting the sub loom from the main loom, and save shed loads of time. It literally took me 45 minutes to fit, though many hours of research!
