I have a 1987 nissan 200sx with the vg30de. Im wanting to swap a ka24e into it. But most importantly, I want to swap the digital cluster. It requires a sub-harness and power module. If anyone has advice or knows where to get these parts, that would be the most appreciated. If you maybe have an idea on how to create my own sub-harness too, that'd be awesome. Im more concerned for the power module as I have read that it's extremely hard to create one as it requires weird things and is sensitive to incorrect signals. I hope there's at least someone here who can point me in a direction. If not, thank you for reading!
