Here's another 4A-GE KP I was working on recently. 16v T-VIS wired in. Might do a write up shortly on wiring one up. The loom needs tidying yet but the car is running now.
Here's a circuit opening relay I made up using 2 relays. Would have been easier to just take one from any scrap 90's Toyota. Below that is the late spec AE86 loom used.
Here is a video of it now running. The loom will be tidied up yet.
