    98 z3 M52b28 into a 99 z3m shell engine harness help

    Recently got a 99 z3m shell and decided to throw in a aluminium block m52b28 and zf that was in my 98 z3. But the 98 engine harness has 3 connectors from the engine harness that plugs in next to the fuse box 2 large and one smaller plug. And the 99 z3m chassis only has 2 connectors one big and one small. Trying to figure it out. Thanks.
