I wired up the Haltech yesterday and today. It took about seven hours altogether. I've ohmed everything out but haven't yet powered up the ECU. It got late and I wanted to go make dinner. I chose to run the wires from the Haltech harness to each of the main engine components (injectors, coils, sensors, etc) rather than using most of Mazda's wiring, to make it easier to debug later if I had an issue. It also allowed me to remove a few extraneous wires from the harness.

Thanks Clyde for taking pictures and for providing conversation and company.





Haltech does a good job labeling wires, but it's not as cool as the printed labels down the length of each wire that the BMW had in its Megasquirt harness.



Peter Florance turned me on to these non-insulated crimp terminals, I love them. Super easy to work with.



Most of the engine-side stuff done, with temporary harness tape "tacks" to hold stuff together.



Ohmed out and portions wrapped, but with some left to go. Coils and injectors are unplugged in preparation for ECU configuration and loading of the tune. I also swapped to the ID1050X injectors while I was in there. The group of wires in the front left are all spare unused I/O that I'm not sure what to do with, maybe coil them up and tuck away somewhere in case I add features later on which require their use.



Lots of factory wiring and scraps of leftover Haltech wiring left over to save for future needs.

I didn't have time to configure the ECU tonight, will get that sorted out this week, get the intake manifold back on and start the calibration process.
