Part was delivered lightning fast, installed as a perfect match in all respects to the original that came with the car (right down to the tiny nylon pins that positively lock the wire connectors to the sockets!). Actually the only differences I found were the insulation (higher quality material and 'cleaner' application) and main transistor (more precise specs and wider operating temperature range) - making these components better than original part!
