*Title should read UZS157 Hi all, I got my hands on a Crown Majesta non-immobilized ECU. Luckily, it had the three rightmost plugs still in it, so I'm able to see which wires were connected from factory as well as the wire colours. Click on the images below for full size. At first, I thought that these plugs might have been out of a different model, but then I found these pictures that confirmed they are correct. I read that this ECU has a similar (if not same) pinout as the Celsior/LS400, however after looking at it, some of the wires are in different places. For now I'm focusing on the rightmost plug (where immo wires would have been). This motor did not have a hydraulic fan, and the ECU does not have an immobilizer or MPX bus, so many of the wires are gone, but it still seems a bit odd (and minimal). Below is what you would expect to see on a Celsior. If I use the Celsior pinout, then the wires should be as follows: Present: 1 - green - D 10 - red - ?? 14 - black/brown - STI- 16 - blue/white - L 25 - green/orage - 4 26 - violet/green - RL Missing: 3 - IMLD 4 - EOM 5 - HP 6 - TH- 7 - TH+ 8 - SOL- 9 - SOL+ 11 - MPX1 12 - CCV 17 - TXCT 18 - CODE 19 - RXCK 20 - KSW 21 - LCK1 22 - TAM 23 - PRE 24 - MPX2 What is the red #10 wire? Does it make sense that this ECU is missing KSW due to no immobilizer? What about the HP, LCK1, PRE, and TAM pins for the A/C?
