minimum wiring diagram

Quick disclaimer, I did not make these, I do not remember where or when I got them, to give proper credit.
Alot of people have been posting where to find this so here ye are, hope it helps.

 

thanks mate thumbs up!

 

Thank you! I was getting frustrated off the rats nest that was there from PO, and this helped a lot to redo it and get it running reliably.

 

No problem, I finally got mine down to what I need left ans am in the process of re-taping everything, the pictures helped me alot.

 

Why is this a minimum wiring diagram, and not just a wiring diagram? What is missing here that a stock wiring configuration has?

 

Turn signals and safety switches.

 

Oil, fuel gauge, tachometer, safety switch, etc

 

Is there a diagram that includes turn signals?

 

not that I know of but it is just power - flasher - switch - split from each side of the switch to front and back - ground.

 

I had the second diagram already and have been looking at it so I can get my wiring right on my bike. Just printed out the top diagram which will make it much easier! Thanks!

 

No problem m8

 

Would you know how to wire front brakes to work the taillights? I have two wires coming from the master cylinder but don't know what was running to it when I removed the fish finder. Right now, I just use rear brakes to warn behind me . Thanks

 

On my '83 XJ750RK Seca, those two wires are for the brake-fluid-level sensor. The original front brake light switch is located at the right-handlebar brake lever.

edit to add: To simplify the handlebar wiring, you can buy a hydraulic brake-light switch and mount it in-line between the master cylinder and the calipers. That can be connected to the brake light circuit in parallel, just like the original.

 

brake switch should be built into the lever and is a push button switch. the wiring for it is in the diagram. power - split to foot brake and handle brake switches - bring them back together to the brake light - ground.

 

I think that after I removed stock master cylinder, and put one on the handlebars something is different, I believe I will go with the pressure switch banjo bolt. There was one on eBay for $20

 

One thing I ran into with these diagrams is that on my 81' maxim the starter button returns the ground to the solenoid. I tried to eliminate the starter switch and put in an ignition. No go on these bikes. Also the taillight and brake light need to be grounded to the frame as well. Just what I have found doing my simple wiring.

 

anyone know how to do this and add just the dummy lights and turn signals? i want to get rid of the monitoring and stuff, but i dont know if that will negate the use of the dummy lights.

 

Which 'dummy' lights are you trying to run? Specifically. I eliminated everything from upfront except speedo, headlight, horn and ignition. Thinking about adding turn signals upfront but at a later date.

 

i really want the oil and the nuetral one if i could dont care a bit about the brights and the turn signals

 

When I removed my dashboard, I kept the harness instead of running new wires and removed the pieces, so I still have the neutral wires Etc. Not sure if you want to do it that way, or if they still work without going through the computer but its worth a shot.

 

XJ750 Seca neutral light wiring doesn't interface with the "computer." The (light) brown wire is fused power and sky-blue wire is grounded by the tranny switch when in neutral.

Edit to add: same color code for XJ650 Maxiim.

 

Hey guys. I did this and have no spark. The only questions I have about it is the wires from the ignitor to the coils. Mine didn't have gray and orange wires coming out of it. It has a blue and white. I tied the white with the grey and the blue with the orange. This is correct right? I haven't found where anyone has made comments about it. Also my ignitor gets rather hot and so does my grey wired coil. Only getting about 3 volts of power on that side. Any ideas?

 

I am have really bad problems with the wiring on my 1982 Yamaha xj750 maxim and I was want to know if anybody was done there bike like this or is it even doable thx u

 

Mine was done based on this diagram.

 

Ok I did the wiring just like the dieagram showes and now my bike won't fire I think it has something to do with the tci box and iam stuck what wire should.be hook up Igot the wires going to coils and the pick up on it but there is a black and whit on the plug and a blue on and a black and red doses thoses need to be hooked up to get spark or what and my tci box is good been check help

 

Hi this post is from a while back, but did you get the bike running fine after the loom alterations? Ive done a similar job on my Kawasaki GT550 and it works fine.

 

82NewToMe was last seen:Apr 22, 2016

by his posts it looks like he was up and running but his post here does not say he had any trouble with the diagram

 

I did it based on this diagram and worked for me

 

Hey buddy, did you start completely over? I have xj700

 

I ended up wiring from scratch. Easier than hacking the original harness.
Just did a complete wiring for a different bike because it is also a good opportunity to replace all pins inside the connectors.
