Spent the past week trawling through the Nissan Service manual breaking down the coilpack loom in order to wire in various things that are needed to get the car up and running.
Typical examples are utilising the OEM rear heated window switch to drive the front heated screen, seeing as the rear window is now Lexan. Also utilising the OEM aircon switch to activate the WiFi module, which allows convenient cable free access to the ECU. That however requires a permanent live supply, so you don't have to wait for it to boot in the event of the ignition being switched off.
Main power feeds are also needed for an internal battery to the starter and main fuse box. I'm still scratching my head regarding final placement for the main fuse and relay boxes. As the cold charge pipe and turbo intake both sit where they are on a standard car.
To help with mockups for now, I got myself a decent race battery, which will fit nicely where the OEM ECU sits behind the centre console. Nice neat solution and saves on passenger seat faff while minimising main power feed runs. Saves another 10kgs out of the car too, as the OEM battery tips the scales at 12kgs and this one only weights 1.96kgs. This is about the same spec as a Varley Red Top 25 but with almost 3x the CCA rating
