can I purchase just what I need... I already use a gm module(4 pin) and a crane e coil. in my duster but I could use(and like) the heat sink you have and any related wiring.
The heatsink has been reduced to a 1/8 x 1.5 inches x 3 inch aluminum plate (hardware store)
And since you use the four pin module and a crane coil my wiring and connectors won't work with your parts.
Sorry
