Comes with everything you need to install this in your 1g. ECU socketed by ECMlink and bought the package straight from ECMlink. USB cable is in perfect condition. ECU was also socketed by them and caps replaced.
Oh and if you have a 90 and want the ECU changed to a 90 we can work it out through ECMlink. It's $75 for the switch IIRC. Either way I can send it to them first and then they can send it to you.
Price for the ECU and the ECMlink V3 setup is $650 shipped. Add the $75 if you want the conversion.
If you have any questions post them up.
