I need some assistance on figuring out the pin out and connections for my new head unit swap.
The lotus harness is a mystery to me.
I have a 2012 Evora NA IPS with tech package, originally the Pioneer AVIC-X940BT but now the Pioneer AVIC-W8500NEX. I started another post but cannot find the lotus harness wiring diagram.
This is the best I have figured out
Sorry I didn't respond to your other post yet. Below is what I found through my research and what I used for my AVIC-W8400NEX (should be the same harness as W8500NEX). What's key is the intended colors for the AVIC-X940BT, which is what is in the picture below, and my link above. The purple, purple/black, green, green/black aren't used by Lotus, so you'll find those areas of the X940BT harness blank. These would be rear speakers.
Use this chart with some masking tape and a marker, go wire by wire on the Lotus harness and write what color it means to the Pioneer standard colors. Then join the written colors on the Lotus harness to the actual colors of the Pioneer W8500NEX harness.
2013 Evora IPS - Carbon Gray
2016 BMW 328xi - Estoril Blue
