Millipede to Centipede wiring conversion. ----------------------------------------- The connector listed below is the Centipede connector. The corresponding Millipede connector location is listed in the brackets. P20 goes to P20 and P19 to P19 unless otherwise stated.

Make sure the cocktail pin P20-15 is jumpered over to ground for uprights on the Centipede side connector. 2. Install a jumper from P19-L to ground on the Millipede connector This is the ground for the Millipede coin mechs. The ground on P19-N is the ground for the Millipede service panel. 3. The P10 connector for the -5 and +12 volts is on the Aud/RegII card. You'll need to buy 2 .093 male molex pins to snap in the molex housing. 4. To access the Centipede color grid, a momentary switch will need to be installed as the tilt switch. The 2 Millipedes I've seen do not have tilt switches. 5. Millipede cabinet uses composite sync whereas the Centipede cabinet uses horizontal and vertical syncs. 6. The Centipede pinout on wiretap shows 'coin door ground' on pin P20-X and Start 2 LED on P20-R. These are not correct. P20-X is +22 VDC and Start 2 LED is on P20-8. I verified this on schematics and on the Centipede harness. P20-R is the TILT switch.
