Help (New Member) - CBR1000F Wiring
Hey everyone,
I’ve browsed the forum quite a bit recently and I’m happy to now be a part of it!! New CBR owner but long time rider. I picked up an ‘87 that needs a good amount of work (though it rides fairly well in it’s current condition), so I decided that I’d just rebuild (most of) it and be able to ride reassured that the work done on it was performed thoroughly and properly. Pics will be posted soon of this bike before, during, and after rebuild in addition to another ‘87 project that I’m picking up this week. I do all of my own work, but I’m having trouble and could use some advice on wiring.... I’m looking to install aftermarket controls while I finish restoring the OEM’s. I’ve ordered and returned 3 garbage pairs of controls from Amazon that they claimed fit the bike...I know this is gonna shock you all, but they don’t (can you believe it???) I just got in another pair that seem to be decent quality, but the left control is still just a 9p. Given that these aren’t necessarily going to be long term, I’d like some advice on how to properly configure the wiring to play nicely with the stock harness... I have all of the manuals and wiring diagrams but electronics is not my strong suit. I know the 3p mini connects to the turn signals and speedometer (lb/w, o/w, br/w). Does anyone know how to properly, or not properly but still functionally, splice the wires to the aftermarket unit? Is there another way to go about this (without ordering another set of controls)? Any help would be appreciated!! -Eric https://cimg0.ibsrv.net/gimg/cbrforu...bb8107ec8.jpeg |
According to the manual I have, the wires to the turn signal switch are different. Is this what your wiring diagram shows?

So that’s the same as I have. If you look towards the bottom of the schematic, where the wires originate, and follow them to their destinations (right & left turn signals, etc) they pass through a 3p mini. That 3p mini is what’s in my pic. It’s part of the clutch side sub wire harness and connects to the clutch side hand controls. It appears to be essentially a 9+3 harness (+2 clutch cables). Disassembled the harness has a total of 14 wires....

@Esacks1 Ok, we're all on the same page. So what information do you have for the aftermarket control? Any wiring diagram or indications as to what the various wires do from it?
|
No wiring diagram with the aftermarket, however it’s not ultimately what would help in this situation. The aftermarket has 3 wires to high/low, 2 passing, 3 turn signal horn junction box (not sure that’s the part name for it), and 2 to horn. In contrast, the OEM has 6 on the turn signal horn junction. That would account for the missing 3 wires on the aftermarket, but doesn’t tell me how to go about making the wiring compatible with the harness on the bike :/

BTW, Welcome to the forum, I forgot to say that. :D
Also, I'm going to move this thread to the CBR1000F forum. Others in that section may chime in if it's moved there. So, do you know how to use a multimeter to check continuity? (I figure you do, but have to ask). If you look at the below image, Notice how the connections are made depending on the position of the Turn Signal switch button. This switch has 2 halves controlling 2 circuits. The running lights and the turn signals. The Red line is just to show the separation of functions. The challenge you have is to find which wires inside the new switch control provide the same type of functionality. Center position, power is provided to the running lights on both side of the bike, Left and Right. So a connection from BAT4 to PR and PL. There are no connections to W, R, and L. https://cimg5.ibsrv.net/gimg/cbrforu...dd81c0efa6.png If you move the Switch to the Left, then you apply power to the Left Blinker portion (filament) of the bulb, and remove power from the Left Running portion (filament) of the bulb. https://cimg1.ibsrv.net/gimg/cbrforu...b3d8b02158.png Move it to the right and you get the opposite. Right Blinker gets power and the Right Running has power removed. https://cimg8.ibsrv.net/gimg/cbrforu...6eb8187c09.png |
Thank you for the warm welcome and for the in-depth answer!!
To answer your question, yes, I know how to check continuity, however I don’t know how to use that information to reroute wiring/circuits. In the schematic I’m assuming R, L, N are right, left, and neutral respectively, correct? As for PR, PL, W, R, L, power right, power left? W? attached are a few pics from the OEM turn signal box as well as the aftermarket. I don’t know why the need for the extra contacts on the OEM but hopefully this helps somewhat... https://cimg5.ibsrv.net/gimg/cbrforu...ac5617ccd.jpeg https://cimg7.ibsrv.net/gimg/cbrforu...7ed20af4a.jpeg https://cimg8.ibsrv.net/gimg/cbrforu...8a40d3c53.jpeg https://cimg2.ibsrv.net/gimg/cbrforu...bb441e01d.jpeg |

The aftermarket has 3 wires to high/low,

It looks to me like you've got it completely taken apart. I'm not sure why you want to mess with rewiring and installing an aftermarket unit. All you need to do now is clean those housings up with a little kerosene or mineral spirits, clean the contacts with a scotch brite pad, add a little grease for lubrication and protection from corrosion, then put it back on the bike. Some things I would point out on these while you've got them apart is to look at the solder joints. Many of them just look like a blob of solder sitting on the metal tab of the switch. This is common on many of the Honda switches. They are netorious for having the solder break off of the pad and just be hanging there. You end up having to clean it real good to remove any grease and then re-solder it again. I've seen it in the Engine Stop switch and the Starter Switch as well. https://cimg4.ibsrv.net/gimg/cbrforu...5b729af1b7.png Can you post up a photo of what you have for the new unit? |
3 turn signal horn junction box (not sure that’s the part name for it)
- Okay, so that covers 3 connected to the turn signals, are Lb/w, o/w, and br redundant? If so, could I possibly just solder jumper wires to the aftermarket unit and connect them to the main harness via the 3p mini connector? Or would I be able to bypass the 3p mini altogether? It looks like the additional wires on the OEM are separate wires for front and rear, would it be possible to bridge them somewhere? I agree with you, the solder joints on the OEM are terrible. My right side control’s starter button is shot so the previous owner had already disassembled the unit and had been jumping it with the exposed wires (Why he didn’t just have it fixed or take 10 min to solder it back on?? Your guess is as good as mine). So I had already planned on cleaning all of the contacts and re-soldering all of the wires. I also planned on restoring the housing which I already started There are a couple reasons why I decided to pick up the after market units and why I’m so intent on getting them to work... - The bike is currently stripped down to the engine, frame, and tires. The OEM controls were part of my plans to restore the bike, but in the meantime I wanted a set to be able to troubleshoot the bike with before reassembly and all of the service/maintenance that goes into a rebuild. If I could get a pair to throw on in the meantime, I didn’t have to focus my immediate attention on control refurbishing and could work on the cooling system, carbs, etc - Why I’m so intent on figuring this out: at this point it’s mostly stubbornness...I haven’t been able to figure it out and that drives me crazy because I know there has to be a way, I just haven’t been able to find it yet. Also, I haven’t seen any Hurricanes that have aftermarket controls nor have I found any articles on this issue, and if there’s another rider out there looking to put them on their bike and I can figure this out, maybe they’ll then come across this and be able to use it as a resource for their needs https://cimg4.ibsrv.net/gimg/cbrforu...3b09103928.jpg https://cimg8.ibsrv.net/gimg/cbrforu...b256ebc0c3.jpg |
