    85 318i swap to an m20

    hey guys i am swapping out an m10 for a m20 until i can afford a m50. it got, i think its three relays together on the left side of the chassis that is wired into the main loom. ppl say its fuel pump relays. i want to know would i need to leave that in for the m20 motor or does the m20 wireloom has it too?

      why waste the money on the m20 now instead of having it go towards the m50?

          The engine harness for the M20 will include the relay sockets that mount on the left strut tower.
          The car makes it possible, but the driver makes it happen.

            this^ and m10 is super easy to wire , just use your old square harness from your m10 "under a cover connected to fuse box" and splice the m20 harness into that so you can just plug the connector into the chassis one
