If you have a manual Vanagon you will have to add
both the Subaru brake and clutch switches.
For an automatic Vanagon, again you will need the
brake switch. Here is what I did:
addition you need to add the A/T Inhibit relay (part of
Subaru stock arrangement from A/T donor) – this relay is
energized when the A/T shifter is moved from D to N – thus
cutting off CC.
there is one problem that must be solved before doing this.
The START signal feeding the Subaru engine ECU must be
picked up after the A/T shifter interlock. The stock Vanagon
wiring picks up START before the shifter interlock and sends
that signal to the Rd/Bk Start wire in the engine bay Black
Box.. If you connect the CC A/T inhibit relay wire before
making this change the engine ECU will immediately trigger a
Check Engine signal and the engine will start surging as
soon as you shift into Drive. It took me a long time to
figure out what was going on
with this connection.
Another key item to keep in mind is that the Subaru
CC arrangement needs a momentary push button to turn CC On
and Off. So this means you need to use the Subaru CC On/Off
switch or something similar. I used a stock Vanagon turn
signal lever with the built in CC switches but did not use
the contact for turning the CC ON/Off – instead I
installed the Subaru On/Off switch.
I mounted the Subaru CC control box under the
rear Westy cabinet along with the engine ECU.
Here is a picture of the controller just
before I wired it up:
