This is page 4 of 4 of an "8v EFI Swap Info" web document (printed 8/22/08 from yankeetoys.org/mini4x/efiswap/efiswap.htm) covering an 8-valve electronic fuel injection swap, most relevantly for a Suzuki Samurai. The top of the page finishes a wire/pin table begun on an earlier page, listing connector pins 19-22: pin 20 is a Black/Green wire for Distributor Ground, pin 21 is White for the Distributor, and pin 22 is Black/Green for Ground (pin 19's entry is blank). Below is an index of linked wiring diagram images from a factory-style manual section, referencing pages 8A-20-0 through 8A-20-8: Power, Ground, MIL, Diags (8A-20-0 and 8A-20-1), Transmission and Emissions (8A-20-2 and 8A-20-3), Fuel Pump and Idle speed controls (8A-20-4 and 8A-20-5), Ignition (8A-20-6 and 8A-20-7), and Engine & Vehicle Data Sensors (8A-20-8). A reader can learn the final ECU/harness pin wire colors and functions for the EFI swap and which wiring diagram pages cover each subsystem. The page contains no year, engine, or vehicle-model text beyond the "8v EFI" title.
