There is a wire which goes from the starter solenoid to the coil, which gives 12v to a 9v coil, only on starting. If you have a 9v coil, the + side of the coil is attached to a wiring going to a wire wound resister on a white ceramic body close to the coil, which reduces 12v ignition to 9v when the engine has started. I believe the wire from the starter solenoid to the coil is white with a red trace.
The relay is not standard Lotus wiring that I have ever seen on any TC or TCS.
