I recently had the task of fitting an ignition key for a Nissan Champ 1400. I thought this was a walk over. Given that I have just done a suspension overhaul as we as an engine service with no sweat.
Alas. It was not to be. The terminals on new ignition key were completely different from the old key. I reluctantly gave that job to an auto electrician and made a note to brush up on my auto electrics.
