So I’ve got the b18c1 in the car and am wiring it up. All the guides as searches i’ve found say to use an aftermarket IM which I know people jaw used this one.
Are there just plugs I leave out? Or doni have to solder plugs from the old harness onto my stock a1 harness.
In the guise it mentions something about welding butterfly connectors which I don’t realt understand.
