Ah ok i thought the plugs looked slightly different on the diagrams at least, will have a look at some actual ecu pictures to compare, used Altezza ecus are expensive over here for some reason £200+ or i would just buy one if they were 50bucks or soThe Altezza plugs/connectos are the exact same as the 1zz 2zz plugs. The header is the same. The only difference is the position of some pins. I have gone through the analysis of the pinouts - 22 terminals have to be moved either on the same connector or to a different connector. I will post something after I have a chance to verify it. Probably doing this with a readily available patch harness makes more sense than repinning the connectors. The triggers and actuators and sensors are the same except for the idle control and a few other exceptions that are unique to the Altezza. Probably the Altezza TPS will work as wired but the APS will have to be re-configured for a IACV instead. I don't see why you would need to "find Altezz plugs to make a harness" as your 1zz plugs will plug right in to the AltezzaLink.
PS. I do think the PanicWire kit is a good value unless you are absolutely skint or you just prefer DIY.
I already have a patch harness from an old EMB setup i could adapt easily enough if the plugs are the same, i am still interested in a Panic kit to make it easier and in case of other issues that may crop up, just waiting for them to give me a shipping quote.
