									                      Installation of the 40421 active programming cable
Note – A VMAP-D with the 40421 firmware is shipped with the option 1 jumper removed - this will bypass
all programming capability – insert this jumper to enable the programming (last page). VMAP active
cables are very sensitive to ESD. Ground the white wire temporarily to the VMAP before plugging in the
cable to the VMAP. Also check the pin orientation of the cable - the row without any pins matches the
VMAP row without pins. (There isn’t any protection if it is inserted incorectly)

1) The cable is very sensitive to ESD – The white bare wire must be stripped and grounded temporarily to
the VMAP board before plugging it into the VMAP – the jumpers inserted in the VMAP are grounded and
are adequate for that purpose. Slide the active (heat shrink) portion underneath the VMAP if possible
(loosen screws – minor scratching of the heat shrink is acceptable.)




3) Once grounded - note the row without pins matches the row on the VMAP without pins - Plug in the
cable into the VMAP. Check and Check it again – severe damage to the VMAP and potentially the ECU
will accure if it is plugged in wrong. (Note – some cables may be keyed to prevent incorrect insertion)

4) Route the white cable as shown - cut and solder to pin 22 (3rd top row ecu pin) (Data Link
Connector/Blink Code output) use supplied shrink tubing. Note - The white wire connecting to the ECU is
issolated from the white wire between the active portion and the VMAP connector.




5) Route the orange wire through the bottom board (notice the wire loop to the top board)

6) Route the orange wire through the top board as shown and solder to pin 52 (marked on ECU) (Closed
Throttle position switch/Idle recognition) use the supplied heat shrink.




                       Insert the option 1 jumper (Enables programming function)

Checklist
  Ground the white wire to the VMAP before plugging in the cable to the VMAP.
  Check the pin orientation of the cable - the row without pins matches the VMAP row without pins.
  Check that the orange wire is connected to pin 52.
  Check that the white wire is connected to pin 22 (3rd top row ecu pin).
  Check that the option 1 jumper is enabled (Programming function enabled).

Note – With the option 1 jumper removed the VMAP-D-40421 functions exactly like a standard VMAP-D-
40420 – all the programming functionality is bypassed.
