Connecting 100mm VDO Tac 2 v8 waisted spark
Connecting 100mm VDO Tacho to v8 waisted spark
ie this type
de wired the dizze so need to hook this up to range rover waised spark ( 4 coil units ) and switched from my ecu ( on the earth ).
Anyone know how to do this ( I have emailed etb as per there instructions ) just thought I would ask the collective .
Option 2 is to feed from my Vems ECU
Many thanks

if my sums are right, you connect any one coil and set rev counter to "2 cylinder" - just one snag as I reckon it only allows 4-6-8
selection. 
so plan 2 is to connect a diode from any two coils to the rev counter and select "4 cylinder" or 4 diodes from all 4 coils and select
"8 cylinder"
note: coils are wired as you have them and the diodes are in addtion as shown
as show below - the orientation of the diodes is critical!
plan 3 use vems - this may need a voltage converter from 0-5V to 0-12 V.
so you know I am not making this up;

Seems Vems is the easy option as the ecu and the tacho is only 3 inches apart I can use one of the p259 ports and get that to switch the 12 v signal
with a 1 k resistor as shown here.
I will get down to maplin at dinner and give it a go.
thanks for your assistance

Ahh thats what my project manager keeps teeling me.
Plan 1 is always the comfotable easy one.
Plan 2 usually means I have to go and do some work and learn somthing ( but usually ends up presenting itself as the best option as above )
Plan 3 is left for defalecting as much flack as possible somewhere else
