That wire bundle looks tampered with. There should be a wire tie holding it together. The red connector isn’t factory.Hoping someone can tell me if this wire connector is factory. Seems really oddly placed for a factory ecu piece but I’m not sure what else would be run into an ecu pin like this is.
it’s the bundle connected to the ecu that is closest to the front of the car.
Red connector near my finger
Lovely, any ideas what could potentially need to pinned into a factory ecu? I can’t think of anything off the top of my head.That wire bundle looks tampered with. There should be a wire tie holding it together. The red wire connector isn’t factory.

The only aftermarket part I’ve seen close to the ECU is a methanol injection system.
port injection. Pretty sure that car was a pure turbo port injection car at one point. Was it previously owned in Florida?
If I remember correctly yes, first owner had it for like 3 or 4k miles and then the second owner got it and brought it up to 29.6k which is when I bought it.
I was looking at the a90 Supra/z4 wiring diagram and I believe there is a wire going there normally so my main concern is if it was aftermarket but as long as it’s supposed to be there and was just spliced into then I’m not as concerned. I’m guessing it was a test car for pure since they haven’t been around that long? Now I’m wondering if I need to check the turbo lmao.
I get Vanos codes also, only when the car isn’t driven for a few days..
It could also be the oil you’re using, I got a Vanos code when I used rotella T6. Switched to 0w-30 and it stopped showing up for me
Also is there any way to identify a pure turbo short of pulling the charge piping and looking at the wheel for additional blades. Since it’s a factory frame turbo. This is what I’m looking at and the machining near the vband in the center is definitely interesting but could be factory. I’m more curious about all the marking on the exhaust manifold bolts and the waste gate
It was
