The electronic ignition is built on a PCB coded 05110121 and measuring 89 × 53mm. This is housed in a 111 × 60 × 30mm diecast aluminium case to give a rugged assembly. Two cable glands, one at either end of the case, provide the cable entry and exit points for the power supply, coil switching and input trigger leads. The first step is to check the PCB for any defects. You then have to decide which version you are going to build. There are six different versions and it's important to choose the version that suits your car's trigger sensor. For example, if your car has a distributor with a reluctor pick-up, use the layout shown in Fig.5. If it has a Hall Effect or Lumenition trigger, follow the layout of Fig.6.
