Time to fix the speedo error. I am out by about 9%. So when driving at 100kmh my speedo reads 109kmh.
So I built the kit from Jaycar.
I broke into the speedo sensor wires, sky blue and grey in the loom on the drivers kickpanel before the M21/E127 connector. I used a D9 breakout thingo from futurlec.com and D9 connector to the speedo corrector. Added ignition +12volts and ground to the D9 as well.

Wiring....
1. Sensor from gearbox (input to speedo corrector), blue to ground and grey to input. This doesn't really matter which way you connect the input.
2. Output side (input to instrument), grey is connected to the output of corrector and the blue is not connected to anything.
3. I am using LK2 and LK5
I found that this worked fine.
I left the settings of the unit all in default.
The only down side is the ODO reads low by 9%. So I will need to correct for fuel calcs and servicing.
