When # 1 sparks so does # 6. The 7M-GTE engine has bank of three coils, the coil on the left connects to leads 1 & 6 the middle coil connects to 3 & 4 and the right hand coil connects to 2 & 5. When # 1 sparks so does # 6, but # 6 is a wasted spark and does nothing. The same applies to the other coils they spark in pairs but one of them will be a wasted spark. Toyota in there wisdom referred to # 6 for the strobe pick up, this saves removing the coil cover that obscures # 1 lead; as they both spark together, it all makes sense now. Firing order just in case someone needs it 1-5-3-6-2-4
