Universal Gear Indicator for '07 Norge

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?

From a past 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 ?

Can anyone conform this?

I need to see a pin diagram for the ECU....
 
Ok, I traced out these pin numbers on the wiring diagram and they look to be correct.

On ECU (Gray B side) #24 is speedometer, # 10 is tach.


OOOps. This info is for non-ABS. Ive gotta search out ABS now. I think it's different.

Here is the ABS wiring. https://www.guzzitech.com/forums/resources/2007_norge_abs.78/download?version=78 It may be easier to get wheel speed sensor data (I'd use the front) from the connections at the ABS unit. Engine RPM should be the same connections at the ECU.

Yes, I have the ABS diagram.

Interesting that Guzzitech wants to charge people to open these donated links!

It's all about making money here.

I think I'll pull out. Stick to the enthusiasts sites.

By the way, you can see all these wiring diagrams free at:

The think is it takes $$ to operate a web site that is this active. Good forum software isn't cheap, neither is server maintenance. Sites that are flat pages (content only, no interaction like a forum) are not so costly.
