Motronic Conversion - wiring question

[rfkellner at snet.net (Rick Kellner)]

Brett, thanks for the information and the reminder to check the
Scirocco.org first for everything!
It does lead me to another question; do you leave those inputs, such as
speed and shift position 'open' i.e. not grounded?  Does the open
circuit generate any fault codes or is the fault code generated when the
'input' is grounded?
Thanks, Rick.

Did you read the tech procedure for doing a cis-e to motronic
converstion
on scirocco.org?

The short answer, is that the speed sensor is not necessary for the
conversion
to work.  I believe it was used for what you state as well as an input
for
the cruise control, and an input to the optional ABS.
