I'm trying to help a friend with a older Norge (2V heads).
He has a Datatool Universal Gear Indicator and is trying to wire it up to the Norge. I am not where I can see the bike or connections.
Has anyone done this who can provide identification of wires needed for connection?
Basically, he needs to know which wire is the tachometer pulse wire and which wire is the speedo pulse wire.
Anyone have a wiring diagram that gives the color code for these wires?

The best thing I can suggest is that you read up on the threads on installing a cruise control on the Norge. There is mention in a number of those posts as to how to identify the leads you're looking for.
Carl Allison's overall Norge wiring diagram is great for the harness, but not so detailed for the lines running to the ECU. You may be able to puzzle out what you need; check at http://guzzitek.org/schemas_electriques/gb/1200/norge_1200/ (http://guzzitek.org/schemas_electriques/gb/1200/norge_1200/)

Look, I don't know how this is supposed to work? The way that the W5AM alters some of the tables, I'm thinking the torque tables particularly but you'd better confirm with someone cleverer like Mark, is by comparing engine speed to road speed. There isn't an actual *Switch* of a mechanical nature as there is on various other machines. This might make using a *Universal* gear indicator considerably more difficult as you'd have to tap into those signals and logic to get a 'Mechanical' system to work.

These electronic gear indicators operate by comparing pulses to the tach with pulses to the speedometer. They are user programmed to match various tach and speedo speeds to the appropriate gear and showing that gear.
I've looked at Allison's diagrams and cannot discern the wire code for the tach pulse or the speedo pulse.
I was hoping some of you guys had already plowed this ground.

Sorry, no. Without being rude I have never understood the need for such a device? The only bike I have had that had one was the Cali 14. I never looked at it! Even with the Cali which once above idle was as smooth as a baby's bum a quick glance at the tach told me whether I was in the right gear or not?
Look, if I can help with this I will, (Although I'm not the shiniest tool in the box with this stuff!) but what does the owner want to achieve and why?

Many people like gear indicators. This situation is not one of arguing with somebody for wanting something that someone else thinks they don't need.
I can help this guy by telling him the color code of the wire (from the ECU?) that provides the speedo pulse as well as the color code of the wire providing the tach pulse.
I haven't delved much into this. I was hoping someone else had already done this and had a quick answer.
Maybe I should check my Stelvio wiring. The codes are probably the same.

From a post on Guzzitech

The Gear Indicator has five pigtailed wires in a common jacket:
RED +12V Ingition
BROWN Ground
GREEN Vehicle Speed Sensor
BLUE Engine Speed Sensor
WHITE Calibration
Strip another few cm/inches of jacket exposing more individual wires. If you have some heat shrink tubing, put two 5cm/2" pieces over the jacket.
Find pin 17 on the body connector. Pin numbers are printed in the beginning and the end of each line of the pins, so the right wire is easy to find.
Heat jacket of this wire with your soldering iron about 2cm/1" from the connector. The jacket will melt, exposing the bare wire. You need to expose about 5mm/ 1/4". Solder RED wire and wrap the exposed wires with a piece of electrical tape.
Find pin 24 on the body connector and solder GREEN wire to it.
At first I tried to connect the tach sensor (blue wire) to the crankshaft position sensor, but it's signal proved inadequate. I had a better luck with ignition signal, so BLUE wire should be connected to pin 10 of the engine connector.
So, from this, the speedometer pulse is from pin 24 on the ECU? The tach drive is from pin 10 ?
I need to see a pin diagram for the ECU....
** edit**
Ok, I traced out these pin numbers on the wiring diagram and they look to be correct BUT THEY ARE FOR A NON ABS BIKE and the bike in question HAS ABS.

On ECU (Brown side) # 10 is tach.
I'm trying to figure out where to pick up the speed sensor.
