MS3PRO EVO on 4th Gen 3sgte Options

[HardHead93]

I just got my MS3PRO EVO in for my conversion to standalone on my 4th gen 3sgte. I am planning on taking my time with this install to make sure all the wiring is correct and clean looking. To help with the install I grabbed a 5sfe ECU and mounting hardware out of a junkyard car to use as a template for mounting the Megasquirt into the car.









Got relays, distribution blocks, and different color wiring for a clean centralized install.




My goal is to wire the ECU up for as many features as possible and once I get good tune running, start enabling the features. I spent the last few days reading the instruction manual and it has me excited with how much it can do.

I have finished building the box where all my connections and relays will go. It will sit where the factory ECU is currently, behind the center console. I plan to mount the Megasquirt either behind this box or in the glove box and run all the wiring to this connection box.


This connection box will be set up to do the following:
- The big black box is a 122 pin connector for the factory harness. Most of the MS3PRO connections will go into there.
- There are 4 relays mounted on this box (fuel pump, AC cut, intercooler fan relay, and warning light).
- The distribution block is for any connections that need to leave the Megasquirt but not through the factory harness.

This will make for a clean install and keep all the factory wiring intact.
