Mazda engine help needed

    Greetings,

    I have a friend contemplating an engineering project 'revolving' around a
Mazda 13-B engine swap into a different car.

    Does anyone have experience with this engine, or could point to a source
for an electrical diagram sufficient merely to run the engine, with no
accessories or diagnostics required?

    Thanks in advance, off-list is fine.

                                            CB
