The DIYBOB is an exclusive breakout board from DIYAutoTune.com that allows you to easily build professional adapter harnesses to connecting the engine management system of your choice to a wide variety of cars. The DIYBOB includes an OEM style connector, circuit board, and an anodized aluminum case to finish it with a professional appearance. This one fits cars with a 55 pin Bosch ECU. See the DIYBOB main page for an application list. Use it to adapt a MegaSquirt, MicroSquirt, or any other ECU of your choice to the OEM wiring. A close up of the connector is below.
