Wiring a new aftermarket coil.

[TooleyS15]

Gents do I connect the positive and negative to the coil from this elec con that connected to the old coil, or do I connect it prior to the gold transistor thing?

i would say like for like coil to coil but i would read the msd instructions and follow them and check the wire feeds match what im after with a multimeter

[TooleyS15]

its a second hand unit so no instructions, I have te + and - on the msd unit but i dont know what the component is that the ignition + and - goes into before the stock coil.

i think its a resistor matey.

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
