Default Enhanced MS2 and Sequential Injection

I'm cross posting this here in the hopes of catching Reverants attention, or anyone else with an Enhanced MS2 configured for a 1990 with a 1.6L.

TL;DR - I want to wire sequential injection and I need help figuring out where to draw the extra 2 wires from.

Any tips on how to add wires into the harness? I'm not in the garage right now but I assume those 2 pins are empty in my 90 since they're unused? Am I over thinking this? Does anyone have a good writeup?

You can use the pins/wires from 2X (yellow/red) and 1A (blue/red) as these are not used by the ECU.
