Hello everyone i just want some people to look over what i have so far for my wiring that i have done for my MS2. I have 2 wires i dont know were they should go so help with that would be great.

Setup is on my SR20DET swap miata running stock COPs.

Pin 2 I am unsure were it should go as i am using the edis.

Pin 7-10,18 i have grounded to both engine and chassis

Pin 19 I see it says its a sensor ground but not sure for what sensor.

Pin 20 IAT
Pin 21 CLT
Pin 22 TPS
Pin 23 AEM Wideband white wire
Pin 24 connected to pin 1 on EDIS
Pin 25 not used
Pin 26 TPS power +
Pin 27 not used
Pin 28 Main relay that also power injectors
Pin 29 not used
Pin 30 not used
Pin 31 not used
Pin 32 INJ 1&4
Pin 33 INJ 1&4
Pin 34 INJ 2&3
Pin 35 INJ 2&3
Pin 36 is connected to pin 3 on EDIS
Pin 37 is connected to fuel pump relay pin 85.

I checked all relays and they are all wired and functioning right.

Here is my wiring for the EDIS 4

Pin 1 goes to pin 24 on MS
pin 2 not used
pin 3 goes to pin 36 on MS
Pin 4 not used
pin 5 goes to VR ground -
Pin 6 goes to VR power +
Pin 7 is connected to MS shield and VR shield

Pin 8 goes to main relay for power + and also coil power, coil power wire has 47 microfarad capacitor that goes to ground.

Pin 9 goes to body ground
Pin 10 goes to COP 1&4 signal
Pin 11 goes to cluster tach on miata dash
Pin 12 goes to COP 2&3 signal

Please let me know about Pin 2 and 19 as i stated im not sure were they go. Also let me know if what i have is wright so far.
