wiring the edis
Hi.
I've just gone to the garage to start wiring up the edis to car sensors etc.
I'm very confused.
The diagram I have shows as picture attached.
The one I'm looking at is as follows.
1.Blue /Yellow Sheilded with 3&4
2.Green
3.Blue/Red Sheilded with 1&4
4.Brown Sheilded with 1&3
5.Blue/Yellow Sheilded with 6&7
6.Blue/green Sheilded with 5&7
7.Brown Sheilded with 5&6
8.Black
9.Brown
10.Green/Red
11.No wire
12.green Yellow
Also GND means earth.What does IDM and CTO mean?
Are the Browns all earths?

Can't find my neat wiring diagram for you at the moment I'm affraid.....If no one comes up with anything later I'll try and find it
for you....Oli.

Can't help you and never realised it had those pins to be honest, so it can't need them to run.
Maybe there diagnostic pins or to sendrecieve signals from another ECU
There is the REV-counter take off, not sure you've got that listed am pretty sure that was green , so that would be the IDM wire

Hi
Ignore pin 2
tacho to pin 11, if you disasemble the plug you can take the pin out of 2 and fit to 11
All earths should be brown, the shield or screen is just a copper braid that surounds the wires
Have a look at

Its a simpler drawing

Thanks chaps.
I'm using Megasquirt with it's own tacho feed so can I also not bother with the tacho wire from the EDIS?

Yes its not required for operation but you will need a signal to drive your tacho, does the megasquirt output one?.
IDM is the OEM diagnostic signal that the edis signals back to the main ECU

I've used the EDIS tacho signal for my gauge. (CTO = Clean Tacho Out)

Yes it should work ok to drive the tacho as thats its original pupose.I tried to use it as an ignition signal for the megasquirt and found it gave
erratic behavior and the megasquirt thought the engine was running when it was not for some reason.
I ended up taking the signal from the megajolt that I am using for ignition control, and driving the Tacho from the coil leads via some diodes.
