Default Test wiring picture

For anyone who would like to test the SSEI dashboard out of the car, I found some generic wiring schematics, and with some trial and error, pinpointed the connections needed to power the dashboard. Image attached. You can solder thin speaker wire to the points indicated in the picture, press the circuit board back on, and test away - flex board, resolder suspicious spots, etc. There'* up to 42 volts on this board at certain points, from a step-up power supply, so be careful and proceed and your own risk. Oddly, if +12 isn't connected simultaneously at A1 on connector 1 AND A1 and A10 on connector 2, the dash will not "power up". Just twist the +12v wires together that will go to points on the picture.
