After having an MC18 startor, connecting to the PGM3 loom is impossible due to distance of the loom plug. The solution is to make 4 extension cables with the proper connections on each side. 4 defferent colors will be more safe as you will know which one gose where on the other side. this stands for the Distributor plug and startor plug.
