I would like to install the LS2 truck coils in my 97 Miata with a 99 engine. When the turbo is complete, I am hoping for around 300 - 320HP.
My 97 wiring harness has TWO connectors into the existing OEM coil. One has YELLOW/BROWN, BLACK, BLACK/WHITE. The other BROWN, BLACK, BLACK/WHITE. Using Brain's thread I figured out the following:
Brown/Yellow -- Coil 4 & Coil 1 (TRIGGER)
Black/White -- Coil 1 & Coil 2 & Coil 3 & Coil 4 (12V SWITCHED)
Black -- Coil 1 & Coil 2 & Coil 3 & Coil 4 (GROUND)
Brown -- Coil 2 & Coil 4 (TRIGGER)
Looking at the diagram for LS2 coils, I can't figure out how to match the wires. I will be using a MS3X with a pigtail to plug into 97 OEM harness.
Any help is much appreciated.
PS. I am planning on buying the following coil connector harness
