TECH : Request for Help about MFA

[txrocco@sbcglobal.net (ATS - Patrick Bureau)]

Okay so the wires from the stalk go to the cluster correct, aside from
inputs from oil and air temps?

see with the digifiz. I get confused because well wires are the same colors
at all (golf 88 thing) hehehe....

ARrrrrrrgggghhhh!

back to the garage I go...

=>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!)
