Building the wiring harness was arguably the most difficult part of this project so far. I'm using a flying lead kit from ECUMaster which definitely made things easier since the wires are color coded and labeled.

Here's the shielded sensor wire termination & junction with the sensor ground.

Shielded wires made up the base, then I started twisting the first layer of other inputs, ground and 5v.

Coil and injector wires are the top layer.

I got eager with the Raychem shrink wrap and forgot to add service loops by the ECU 😑

This bus bar collects all the ground wires, then connects back to the chassis & negative battery cable from the trunk in a star point fashion.

Overview of the work in progress. Lots of clean up to do of the original wires & fuse box area.
