Hello all. I am wiring LS1 coils and in stock form, each 4 coils are grouped into one connector that has one power supply pin. When I checked the power supply wire of that pin, it seems to be 18 AWG wire.

Is it correct that LS1 coils are supplied with 12V using 1 18 AWG wire which is then spliced to each of the 4 coils?

I don't want to wire the group of 4 coils using the wrong wire size but I also want to use the smallest possible wire size
