Wiring a new aftermarket coil.

[umpkin]

its called a power transistor. it amplifies the signal from the ecu. dont know if you still need it or not with the after market coil, just got that info from the manual

I'd have thought after the power transistor too just like the old coil. Give the grounding points around that area a good clean too while you're there as mine failed to fire when the grounding point to the power transistor was dirty
