I built my own wiring. Get a 4 gang relay box to take place of the ccrm and build your own engine wiring harness. The harness that you get with the megasquirt is laid out great and all the wires are labeled. Im curious how the gauges will work if the stock ecu isnt running all the engine parameters.
As far as i can remember, the ECT, oil and RPM pass through the ECU and just "advise" it of what those particular values are. The Ecu does have complete control over the Speedo and the fuel pump though.
the returnless fuel pump system is the biggest unknown at the moment on making that work.
