5 GT Turbo Renix ignition module tacho output

[Neal R19]

Alright all, does anyone have any info about what is the form of the tacho feed from the renix module to the cluster?

On the 19 (and I guess probably others), there's a pink wire that basically goes from one of the pins on the module straight to the dash cluster to drive the tacho.

I need to know what the form of it is. Some sort of square wave? 12V pulses? Some kind of damped sine wave?

I don't have a running Renix equipped car and even if I did I don't have a scope at home!

tbh the info will (or should) all be in the adaptronic documentation but I don't have adaptronic so I don't have that info... and there's no incentive for me to look for it.

Its the same signal as the trigger to the ign coil, there's 3 ign outputs and I use 1/2 for wasted spark. 3 is configured for tacho.

How about I incentivise you with beer?

So in caveman terms I need to connect what to what

I ran ign3 to the OE coil pack and use that to drive the tacho, Neil is doing that without the OE coil pack with his relay coil solution.
