EDIS4 On A 99' FTMFW

Made an adapter to mount trigger wheel, mounted trigger wheel, built bracket to hold VR sensor, mounted VR sensor. Mounted coil and ignition module. Then wired it up.

12V+ switched power via a relay to ignition module
Ground
+ side of VR sensor
- side of VR sensor
1&4 side of coil
2&3 side of coil
+12V switched power from above also drives coil

7 wires later I turn the key and....

IT STARTED PERFECTLY!!!
It makes spark. I still haven't ran the two wires to MS for spark control, but it fired up in limp mode (10* BTDC) and ran. Course I have the intake ports blocked off with steel. I just sprayed some carb spray in the injector ports to see if it would start and it did. I'm very happy with it. **** works and it's simple. EDIS is the ****.

Congrats. yes, its a simple and elegant design. I am using a 1st gen eclipse turbo coilpack. It is the perfect upgrade for edis plus you can use the miata's spark plug wires with it.
