Article [13] ST1300 - Quartet Harness Pinout

I know this is a really old thread but just wondering if anyone knows what the pin-outs are for the 9 pin connector on the Quartet Harness. All the pin-out diagrams I've found on the net show 5 pins at best. What are the other 4 used for? The reason I ask is I was looking to install a Scorpio Alarm system (http://ridescorpio.com/secure/) and was wondering if this connector has all the pin-outs I need (I don't like cutting into wire harnesses if I don't need to).
 
Is the "turn signal" voltage on the 9 pin connector +12 volts pulsed like its coming from the output of the blinker OR a solid "high" as if its coming from the input of the blinker?

Thanks
Michael

If I would like the power socket live at all times does anyone know what colour socket i should move the plug into
I am asking this as its going in next week to have my valves checked and while the Tupperware is off i would like the mechanic to move it across

It's easy enough for him to check - I noted once that my colours were different from the ones posted on here, so I always check what does what if I want to connect anything new.
 
I can't source male Hitachi plugs locally. Would there be any harm to simply cut the quartet harness white connector off and replace it with a 3 prong plug that I can find locally? 3 Plug is a 3 plug as far as I'm concerned? I can probably find a male and female 3 prong plug at princess auto ( hr freight equivalent in Canada).
 
You absolutely can. The electricity doesn't care what connector it flows through as long as the connector is sized properly and can handle the load.
 
I dispensed with the origina quartet harness and made my own version that plugs into the 9 pin connector. Mine has cables that are the correct length for where I want the accessory to be plugged in - ie somewhere accessible ! - and there are more connectors. I worked out what maximum current I could feed from each. I stuck with the hitachi style connectors that Honda uses - but anything that works and can carry the (rather small) current.

But many auto electrical suppliers on line have the same design connectors available - they just call them something different.

Thanks gang for validation. I will make one more attempt to find proper 2.8mm electrical connectors locally then if I can't, I will cannabilize my honda quartet and just add whatever pin connectors I can get locally. I also considered keeping the original connectors and just using something like posi connectors to tap into the wires. I have not seen those before, but they seem very useful, waterproof, and looks like it makes a good connection.

I personally wouldn't do that. I know that they are used successfully all the time but, to work properly they need to damage the wire that they are tapping in to. This is by design, and is something that I choose not to do.

If you do want the Hitachi type connectors to plug in to the quartet harness, you can get them from Cycle Terminal in New Jersey. He normally has them in stock and my experience has been that he ships them out quickly and that his shipping charges were very reasonable.

I installed a quartet connector bought on ebay, bought plugs from two different sources, and keep getting intermittent current from all three of the sockets on the quartet. I finally gave up on adding a power outlet at the forks, it the Tupperware back on so I can ride.
What am I getting wrong? The wires seem very solidly connected to the plugs. Should I replace the sockets with ones from the same source?

You might have a weak ground.
There is a yellow ground cap behind the right headlight under the front cowl. I ran a 16 gauge wire from that ground to the bike frame for better grounding on the front of the bike.
Honda went with a skinny looking like a 18-20 gauge green wire for a ground wire to the frame from the front of the bike.
To me, it was not the correct size wire gauge they used as they made the bike so we can add accessories to the front of the bike .

I agree with Al, check that ground bundle. My 03 hadn't had the fix, I soldered a 14 AWG wire to the existing grounding bridge strap thingy and put an eyelet on the wire and grounded it to a nearby bolt.

Also, I just went through a similar issue upgrading my GPS. I had purchased one of the cheapo Amazon crimp termainal kits that had the factory stye plugs, and if I took the pins out of the shells and mated the wires, it worked, if I put them in the shells, no worky. I tried to verify they were mating cleanly and the terminals were fully seated in the shells, but no change. I had already put all the tupperware back on and had very little wire to work with, so I slid the terminals together without the shells and used some of the solder heat shrink connectors I had on hand. Ain't coming apart now:biggrin:
