37 megasquirt relay board wiring diagram

There are two ways to accomplish this: 1) Modify the engine bay wiring, or 2) Build a relay trigger circuit. 1) Constant power goes into Pin 86 of the Main Relay and needs a ground connection on Pin 85 to complete the control circuit (triggering the relay). MegaSquirt is already providing power out of DB37 Pin 37 to power the fuel pump. The MS3X/V3.57 is an ECU based on Megasquirt-3 technology, consisting internally of an MS3 card and an MS3X expansion card installed on a surface mount V3.57 mainboard. This manual covers MS3X/V3.57 specific installation details and should be used in conjunction with the general Megasquirt-3 Setting up and Megasquirt-3 TunerStudio reference ...

The only thing that will be connected to the coil negative is pin 36 (terminal 11 on the relay board), so that megasquirt can drive your coil. And for the fuel pump wiring, the relay board diagram shows that terminal #5 is really for the fuel pump, and you can just power the coil off of it if you wish. PWM IAC Wiring: To wire this up without the relay board (directly to the ECU), wire up the hot wire from the idle valve to switched 12v+ (hot in RUN), and wire the negative wire from the idle valve (stock EEC pin 21) directly to pin 9 on the MS3X DB37. This uses the PWM idle driver on the MS3X board. Traction Control.

This will go through a relay in order to turn on and off the MicroSquirt ® EFI controller, and the power source for the +12V on the relay needs to go back to the battery, or a path that leads direct to the battery without a long run of wiring. Just like for the grounds, run a separate wire from the relay direct back to the battery just to be sure. Sending the injectors 12 volt power with the Megasquirt ECU off can result in damage to the flyback circuits. The wiring diagram below shows one way of modifying the stock wiring so that the ECU and injectors power up at the same time, and also allows the other components drawing power from the ECCS relay to work as normal.

Thought this might be of use to those of you going the way of EFI. I bought a Megasquirt Relay board as a simple way of getting power to the injectors and EDIS I plan on using in my EFI conversion. When I got the unit, it quickly dawned on me that just leaving it in the open was foolhardy at best. The norm (to me) with a V3 PCB and EDIS is to use the tach input (DB37 pin 24, marked 15 Tach/ign on the relay board) for PIP, and the ignition output (Pin36 DB37 marked 11 S3 on relay board) for SAW. With the appropriate links on the V3 PCB. Because MS is so flexible, it would be impossible to print all the options on the relay board PCB.
