=>Since we are on the subject, I have an MFA and the speed sensor does not
=>seem to work. What does the sensor connect to and where?

=>>=>Patrick,
=>>=>
=>>=>Here is some information on those wires from my notes of when I did my
=>>MFA
=>>=>install (almost 2 years ago):
=>>=>
=>>=>mfa switch:
=>>=>T7a/2 -> G/BK T4a
=>>=>T7C/1 -> GY/R T4a
=>>=>T7/3 -> GY/Y T4a
=>>=>ground -> BR T4a
=>>=>
=>>=>outside temp sensor:
=>>=>T7/2 -> BR
=>>=>T7/4 -> BK
=>>=>
=>>=>oil temp sensor:
=>>=>T7b/2 -> G/BK
=>>=>
=>>=>T4a is the four-wire connector that you're talking about,
=>except I think
=>>=>the info above is for the other end of the connector (not the
=>switch end)
=>>=>and the wire colors change between the two.
=>>=>
=>>=>T7, T7a, T7b and T7c are all connectors on the gauge cluster. I can't
=>>=>remember how they're paired up but each physical connector has two of
=>>=>those four, one on each "half" of the connector. Kinda hard to explain.
=>>=>
=>>=>You will definitely need a bentley to dicipher this information.. and I
=>>=>can't guarantee that it's correct, since my car is an '87 16v scirocco,
=>>=>my gauge cluster is an 8v mutant-cluster with 16v 8k tach and 140mph
=>>=>speedo and the mfa portion is from an '86 8v golf. IIRC, though.. the
=>>golf
=>>=>and scirocco wiring colors were the same.
=>>=>
=>>=>If your car did not come with MFA, the harness will not be there, you
=>>need
=>>=>to pull it from a junkyard car. So don't plug the 4 wire
=>connector in to
=>>=>anything without knowing its for the mfa first! The cruise switch uses
=>>the
=>>=>same type of connector, so be careful.
=>>=>
=>>=>I did reverse-engineer the wires for the cruise switch (and I can give
=>>you
=>>=>a meaning for each wire if you want) but I didn't bother with the mfa
=>>=>since i had both bentleys at the time and I just wanted to get the mfa
=>>=>working.
=>>=>
=>>=>Hope this is helpful somehow (i doubt it!)
