did you swap the steering column with the key barrel ? This would then plug in to the harness. If not look under the clap on the barrel drill out the studs, there M8 threaded holes so just drill the heads off. Then just fit the barrel to the electrical pugs in your car and see if it starts. you can machine the heads down on two M8 cap screws to re fit the barrel to your steering column

or give me a buzz I walk you through it 0407074141
