What is this connector for???

[Veez_strom]

I am rebuilding my 1978 GS750 using a 1977 GS750 as a parts bike.

I rewired the bike with the '77 harness, engine, and speedo cluster.

There is a 4 wire connector that resides around the coils. It is not present on the '78 and I can find no mating connector anywhere on the machine.

The wires are orange, yellow w/red tracer, black with white tracer, and green with red tracer.

Can anyone school me on what belongs here?

Thanks,

Tom

Can you post some pics ? It would help greatly.

Tom,

I just took a look at the wiring diagram in the factory service manual that you can download from BassCliff's site and found your connector on page 178.
It is apparently connected to ... nothing.

Here is the connector:



Here is the rest of the diagram with the connector's wires highlighted. The Orange wire is connected to a 12-volt wire that feeds the brake lights, turn signals and horns. The Black/White wire is a ground. The Green/Red and Yellow/Red wires disappear into the harness and connect to nothing.

I wonder if that harness is the same as the one used on the 1000?? the 1000 has (or originaly had as most were killed) a turnsignal mider buzzer thing the 750 did not have.

I wish I had not lost my vast collection of GS wiring diagrams.
have to re-build it.

the self cancel turnsignals had two wires going to the instruments where the magnetic reed switch goes but the colors are differant, and the control module has more than four wires.

That's for the diagnosics computer to plug in. Yeah, that's it...

Yeah, I'm sure. They were just waiting for the computer to be invented so they could plug it in.

Japanese bike... They had computers, and giant robots, and all that stuff, even back in the 70's. ;-)

Hahaha.

Of all the people on this board, you would have thought that I would have been the one to think of that!

After all, how many others on this GS board pull trailers?

Steve,

Don't beat yourself up over it!! It just looked right to me being that it connected to the lighting circuit......

[Veez_strom]

No trailer at this time. So long as it isn't something I need at the moment to get the beast running again.....

Thanks :-)

Maybe a harness for a fairing. Factory plug-in type. Just a guess.
