N46 --> m54

Started to upgrade my N46 to a M54, so far is a straight forward swap, engine is from a crash damaged 2001 330i and is going into a 2004 Convartable with blown headgasket, both are manual.

Some electrical problems is anyone could help

1 What to i do about the Ecu plugs being different, have read to cut the plugs off and match the wires?

2 The things that look like motors mounted to the inner wing and connected to the heater matrix pipes, The M54 has got one and the N46 had two

3 The wire going to the A/c pump is under the winscreen washer on the M54 but its part of the engine loom on the N46



And will the coupe exhaust fit ?
Will it survive without the alternator cooling duct
