Wondering if the new stock main engine harness needs this black box plugged in inline with the new harnesses? I thought I read the new harnesses had this stuff built in, is this true?

Thread that Dale talks about the updated addition to harness.

anyone know if we can omit the black box when using a new mazda harness?





Thanks again Dale for the PDF TSB from that thread!
