We are constantly asked to provide wiring diagrams for non-M E46 S54 swaps. The following chart was created to assist in any wiring changes necessary for S54 swaps in to MS42, MS43 and MS45 vehicles. Please consult the BMW WDS before making any changes:
Yesterday we launched the Wiki www.S54swap.com. S54Swap.com will serve as a reference for all who wish to swap an S54 into an E30, E36, or E46. Additional models will be added in the future as working configurations are submitted! Check it out and submissions are welcomed!
