Bonneville gauge questions

The T100 had the speedo/tach combination, but you might need the short wiring harness from the headlight shell to the gauges unless you have the three wires already there. If you need the bracket and tach, PM me as I have them.

Read the instructions for the accessory tachometer kit for your bike. I had a 2005 to which I added a tachometer, using the factory kit. You need all the parts in the kit except the long single wire to the ignitor.
PM me if you can't find the tacho kit instructions. I might be able to find them.

Did you get my last post,
Yes, I got it. There are actually two grey/white faces for this bike. The differences are subtle and you do have to look at it to notice. I am trying to get a couple of photos to send to you.
Were you able to establish if the "extra" red wire from the igniter to the plug in the headlamp shell was present?
Haven't gotten into the headlight yet. Will look this afternoon or tomorrow AM latest.
Appreciate your efforts to determine cosmetic differences in gauge faces. Were you able to look at the picture I sent you?
Just to let you know I am interested in buying what you have.
Yes I got it. If I can get one of my friends to take some photos of what I have then I will send them to you.
It might be easier to remove the saddle to see if the wire runs between the ignitor and the headlamp shell. If you can get a good close up of the ignitor plug then I should be able to tell.
Do you have a Haynes manual? They are invaluable when working on these bikes. I inherited the Triumph workshop manual but I wouldn't recommend it.
Interestingly, I am trying to track down a pair of early Thruxton gauges as I prefer the white face!

I don't have a manual of any kind as yet. On my list.
I also have a recently acquired 2016 Thruxton. Both bikes kind of fell in my lap after searching for a long time.
If the tach that you have is close in appearance to my speedometer then I think we are golden.
I do not care for the offset mount on the speedo. Like more symmetry. Maybe I'm just a little wacky.
There have been several posts regarding the wiring on the tach and it all sounds pretty straightforward to me. I will start in the headlight and,if needed, work back from there.
Your other option is an electronic speedo mounted centrally. Can be made to work with a mechanical speedo drive.
I prefer the dual gauge symmetry too, it has looked right and balanced for decades.
Ok got into the headlight . No unattached red wire there.
Pulled seat. Just an evap relay there and an unidentified relay.
Fuse box under right side cover, starter solenoid under left.
On my 2003 Speedmaster the igniter box is mounted to the frame under the gas tank. Can't see it from underneath but not ready to pull the tank yet.

Yes, that's the ignitor.
You don't need the "extra wire" for a 2006. It's built in. See my post #3 above.

It looks like the "extra" wire is there. The next step is to locate the plug in the headlamp shell, that's the one where the wiring from the gauge cluster (warning lights etc.) plugs into the main harness. You should see one red wire on the main harness that does not go up to the cluster, that's one of three that you need for the tach. The other two are a switched feed (green with a red tracer) picked up from the oil pressure and neutral lights and a ground (brown but changes to black), picked up from the instrument light and high beam warning light ground.
Interestingly, it doesn't show the "extra" wire in the wiring diagrams but it is there.
So the connector is already in the housing where the indicator lights are?
Should be good to go on that based on what I found earlier.
Not necessarily. The wire runs up to the plug in the headlamp shell, but there may not be a corresponding wire in the short harness that plugs into it and goes up to the gauges. Does this make sense? It's a bit difficult to explain until you look inside the headlamp. Count the wires on the plug in the main harness (11) and compare that with the number of wires in the short harness plug (10 or 11). Either way, the hardest part of the wiring is done.
There is a red wire on the side of the connector going to the gauge and indicator lights. Pulled back sleeve to confirm.
