Cas wiring/ No rpm MS2

hey guys i just finished up My megasquirt mods as per aaron cakes guide

and everything seems to be working tps, Coolant

The 24 tooth wheel Has 2 different ways to be hooked up? I assume it would only have one way and the 2 tooth wheel would have the multiple ways? (because you build this circuit)

So im confused when i look at these 2 wiring diagrams

When you follow a Megasquirt writeup, you need to only follow one writeup.

The external wiring diagram on my site matches the instructions on how to configure the Megasquirt internally. The PDF instructions have a different wiring diagram because the PDF instructs you to configure the Megasquirt internally a little different.

If you intend to use the external wiring diagram from my website, you need to follow these instructions to configure the Megasquirt internally:

Ill post the msq when i get home

the pots are fully counterclockwise to just before the click

No composite log, i get nothing from the triggers its as if its not connected... im going to triple check the harness but i cant see it being in there

the only thing im not 100% confident on is the MS itself

Again ill post the msq when i get home maybe its something obvious in there

Getting nothing from either of the triggers is highly unusual. I've never seen it happen when the MS and the harness are built correctly.

I will check the settings though.

Do you have any diagnostic tools such as a scope or frequency counter?
