I'm having a professional Mega Squirt tuner build my system... He told me this. "My system plugs into your harness. You will need an air temp sensor, tps and
the balancer sensor setup off of M30B35".

My question is do I have to also change over the harness and MAF from a b35 to make those items work or is his list ALL I need for his MS2 tune to be plug and play for my 87 e28??

the maf won't be used. the iat sensor takes it's place with a vacuum line from the engine to the ms2 ecu. You shouldn't have to change the harness inless you need wiring for the front mounted crank sensor. With my MS2 from PFTuning I used a harness from a supereta.

Mines an e30 with m30b34.

You need to ask your professional MS tuner.
