Build your own 192 x 64 display power harness
Steps
- You need 5 feet each of 18 gauge red and black wire, a 5-pin and an 8-pin .156" Molex housing, four crimp pins and heat shrink.
- Unplug the old connectors at controller J1 and power supply CN5; they are no longer used.
- Form each colour into a loop by soldering its ends together and covering the joint with heat shrink.
- At one point on each loop, bare roughly a quarter inch of insulation, leaving the copper uncut, fold it and crimp and solder a pin there; add a second pin 2.5 feet away, opposite the first.
- In the 5-pin housing for J1: red (+5 V) in pin 1, black in pin 3; pin 2 is the key.
- In the 8-pin housing for CN5: red in pin 8, black in pin 2; pin 7 is the key.
- Plug the housings onto J1 and CN5. Instead of CN5, the IDC plug at CN6 can take the black wire at pin 1 and the red at pin 10 (key at pin 5).
