I am having a real tough time finding a replacement speedo for a scooter I am repairing. I can't quite find the exact one. Here is what I have -   I can't find one with the right wire layout or one that has a back like that. If anybody knows where I could track one down that'd be a big help. |

I think I might have what you need . I'll post some pix in a bit .
I know it's not exact same but might work .

That might be it. The gauges are so far gone on mine I'm not even sure if I have a tach or if thats fuel gauge on the right? Here's close up of my connector if that looks the same to yours or not.  |

mine has a 9 pin plug and a 3 pin plug. I have a brand new lens cover that I found on ebay. from China . paid through the nose for expedited shipping - took even longer to get here. 5 weeks. $35.00.would have been about 22 maybe . I can't tell how many wires/pins your plug has . looks like it is a 9 though. speedo on left , tach on right    don't throw any of your little screws away for the back of it ; not sure where mine are .
got a brand new cable too. has probably less than 100 miles on it. just guessing

Ya that looks different than mine unfortunately. Mine just has the one 9 connector. Thanks for your help though

you might not have to write it off yet. I'll look and see what the 3 pin plug is for .some accessory maybe that you don't have or need .maybe you can just not use the 3 pin and all your lights etc, will still work fine . you should ask here .
I'll go look , soon as I finish eating.

jloi is on the right path
I would prioritize if it will fit asethically .
If you have a wiring diagram you could swap it over these are all dc connections .
If you don't have a wiring diagram it will just take longer to check continuity .

as a matter of fact I have a "generic" wiring diagram for a gy6 150 that I'm following for my conversion to naked and making new harness from scratch. It's not exactly the same - some colors are different , but for my purposes I may be able to figure it all out.
I don't know yet if it would be of any use here with dejavu165

ok, it's too difficult to try to exolain but I think , with some work figuring the wiring out this cluster could be used on your scoot. I do believe the cluster /plastic itself is the same size/dimensions . there are also 2 little tabs broken off from the perimeter and 1 remaining . I think those tabs are for holding the lens in place; they just snap in. I never had any trouble with the lens being loose tho. also , with a little ingenuity they can be repaired .

Unless you have one of the popular models, finding a replacement cluster is like looking for hens teeth. I figured if I was going to replace a fuel gauge or speedo/odo, I would get a low-budget generic for a Taotao.
I would then pull the needles from the gauge pin, and remove the gauge from the cluster. Swap the gauge(new/working) to the old cluster housing/face plate, and re-attach the speedo needle or fuel gauge needle. Figure out the wiring, and it should be good to go. You can reset the odometer reading if you are a stickler for accuracy. It means some disassembly to rotate the tumblers as needed, and then re-assemble.
If you don't mind the wait, you can get a generic cluster for less than $20, which should be suitable for parts donation to a defunct cluster. I have one machine, that has 13" wheels, a "Victoria" that has a triangular cluster that lacks a faceplate and has defunct speedo and fuel gauge. Not sure if it's worth the effort as I cannot find anything about it, and have zero plastic to cover the gauges if I did my 'swap'.

Well, I decided to take your advice and use a old generic cluster. Ive been connecting the wires and its been a straight ahead with the ones that are the same color. But I am having a hell of time figuring out what 2 of the wire out of the harness are for. One is yellow/black and green/yellow. And what I have left from the gauges are the brown for the lights and the blue/white for the fuel gauge. But connecting and combination either isn't working or is blowing fuses. Also I ripped the old cluster apart and I am realizing that is some sort of lcd gauges.. I have never seen that before. Also this scoot is DC. I have been looking at a lot of different wire diagrams but I don't know if that matters.

If the old cluster had a tach, it could be it used the yellow/black wire. From memory that is the one connected to the CDI signal(fire) which operates the coil. A tach would need that signal to know the rpm.
I think I would use a meter to check the voltage/signal on the two unknown wires before connecting them to anything. Set a VOM to AC volts/20, ground one meter wire, touch the unknown with the engine at idle? or with the key ON/OFF to see if it carries voltage. The ON/OFF test would be DC voltage from the battery as there is no AC floating around when the engine is not running.
If you get any AC signal, it may be lower V than the 20V range... and you'd have to step back down to see a signal. If you have a Hz setting on a VOM, it could then be monitored to see if it is indeed a tach signal, varying frequency(Hz) with rpms.
In short, quit connecting to 'whatever' without knowing what it is. You could cook stuff, and have to spend $$ to repair the magic smoke leakage. Find a Kymco schematic, they use DC CDIs, and many have Tach connections.
