Re: Alternator light on in park or neutral: From post #15372 on the Subie Vanagon list: 

"Just a follow-up post. After conversion I had an alt light on after 
start in park and neutral only; alt was putting out regardless. 

After some study of Bentley, I added the extra diode (from the 
Radio Shack 3 pack of diodes for the tach fix) to one coil wire of 
the VW oem cruise control relay, between the alt light and relay in 
the circuit and blocking from the alt side, (the other side of the 
relay coil gets power ftom terminal 50 of the start/ignition 
switch). 

The relay actuates during start and no more alternator light, yay. I 
can only figure this relay prevents (or interupts) cruise control 
operation during start, as it is N.C. at all other times. 

I took starter engaged power for the Subie ECU right at terminal 50 
of the starter, so the alt light may have been looking at something 
in the ECU through the cruise control relay". 

Hope this helps Wildthings, sorry for the highjack
