| 1. Have a simplest audio fischer OEM adapter to have the right connectors available for example (MATCH PP-MB 1.9MBUX-BUR )[https://www.audiotec-fischer.de/en/match/adaptors-harnesses/pp-mb-1-9mbux-bur] | |
| 2. 9 pin connector uses only 8 wires - these for 4 subwoofer wires (8+8 double coils), and 4 for front woofers (2 left, 2 right) | |
| 38 pin connector only has about half of the connectors used by the look at it. | |
| 3. Important bits are orange wires - one with a purple stripe and another one with a brown stripe. | |
| These should be automotive Ethernet one. | |
| 4. The are automotive Ethernet, because they lead to microchip TJA1100. | |
| 5. TJA1100 is NXP's microchip to provide 100BASE-T1 PHY for Automotive Ethernet. | |
| (has reduced maximum length, but only requires 1 twisted pair). |
