It's rarely anyone's favourite job, but I started doing the wiring loom for the new injection system. I'd bought the half loom that was available with the OMEX600 ECU. This consists of the multipin connector populated with pins and wire. The wire is good quality and colour coded for easy identification, so the bulk of the work consists of cutting the wires to length and either crimping on connectors or splicing to existing wires. Locating the ECU and relays took a couple of iterations.

I still need to figure out how to route the high current wiring as I intend to relocate the new Lithium battery at the back of the car.
