955i Daytona Speedo Help - Digital Conversion

I’ve posted a link for you in your newbies thread mate.

 

You cannot use anything from ~ 2005 onwards, these are all CANBUS style instruments that will not accept any analog signals for speed or tach. So those examples you cited will definitely NOT work - their speed and tach info is on a digitally encoded data-stream from the ECU and there is simply no way to integrate that to utilize analog inputs directly

You have a couple of other options however:

1) Simplest, is just to replace the speedo clock (in the TRi-cluster) with an electronic one from a Sprint ST (99-04) - the speed sender from same bike is a form & fit replacement for the mechanical drive speed sender on the front axle
The Instrument itself is not quite a direct swap, but it's not that difficult from either physical fit, or electrical connection. (you will need to add a switch for the trip reset also)

1a) Similar to 1, but using an after-market gauge - this one looks to be about the same size as the OEM speedo - has additional functions also

2) You can swap the whole tri-cluster assembly for a digital set from an 02-06 Daytona (the Daytona, Speed Triple, Sprint RS and TT600 are all essentially the same - but the Daytona one specifically is going to be better matched in the RPM scale)
Full details of that swap are here - https://www.triumphrat.net/speed-triple-forum/185821-digital-instruments-from-02-onto-97-01-a.html

2a) Similar to 2, but go with a complete after-market type of instrument panel
e.g. https://www.digital-speedos.co.uk/gauges-c4/motorcycle-gauges-c27
(perhaps one of the KOSO line)

Regardless of which route you go, you can use the schematics from my thread in item 2 above to know which signals/colour wires you would use to integrate any modern (but non-CANBUS) instrument

 

Yes, between the Instruments and the OEM headlight harnesses - your best bet is to strip out to just behind the steering head an make up new mini harness for the instruments from there Of course my interconnect digram shows the OEM instrument connectors still in place, but if you're comfortable doing wiring, you might do as suggested and cut it back to behind the steering head (you could utilize a single connector there) - should make for fairly compact harness up to the instrument from there.

 

Here you go - re-did the interconnect diagram for you cutting back to a single connector (that would require a 16-way - you might also consider going with 2 x 8-way)
