We do not make this plug, but we do pay dearly for it! Note the careful solder work involved on those castellations (side pads) on the adapter board. |

It's hard to get anyone willing to even make the piece those pins fit into with such tight tolerances much less install and solder all 100 pins! | ||

The following picture shows the finished result (click to enlarge). Note the machined mounting bar and machined spacers used to secure the board in place using the mounting points provided in the factory ECU case bottom. There is a LOT of manual, custom work done to produce these boards. |
