Dragon's Lair Wells Gardner Momitor: WG19K4921 Wells Gardner NTSC conversion board: P371 Here is were the NTSC P204 wires attach to the monitor Chassis... Pin-1: (Vcc-1) Red: goes to the left side of resistor R355. This is a large resistor in the very back edge of the chassis. (Left as seen from the back). Pin-2: (Vcc2) Green: Goes to right side of R204. You can't see R204 written on the circuit board, but it is between J6 and J7. Pin-3: (Ground) Black: this is an odd one because the wire is soldered into a hole in the circuit board as if it was designed to be there, not just added on. The hole is on the right side of VR302 (V DAMP). Pin-4: key Pin-5: (Blanking input) Dark Blue: goes to the left side of R302. Again, difficult to see 302, but it is just above J22.
