Todd: I have some wiring diagrams available for you to review. I
don't have one that is specific to the 97 but believe that the 96 and
98 are the same as the 97. You'll need to print out the diagrams and
compare each against your actual wiring to determine which is
pertinent to your harness/engine. Once you have the diagram you'll
need to review the components that are required to keep as part of the
conversion (fuel pump relay, main relay, sensors, ecu, etc). Once
you've identified those you'll have a marked up diagram that will
indicate which wires you can cut out of your loom and which will be
required to keep. From there on out its a process of laying out the
components in such a manner as to approximate their location in the
engine bay and routing the wires between the ecu and components or
plugs. I use a plastic sheet which i've marked up with an outline of
the engine bay and location of where the ecu will sit under the back
seat that I lay on top of my work table. Then I start the process of
laying down the wires and taping them temporarily to their route on
the sheet. Finally, once i've got the wires run i start the process
of cutting, soldering, and heat shrinking the wires.
I triple check continuity of every circuit that requires connectivity
using a multimeter before ever daring to believe i'm close to done
with my splicing.
I am fairly lame at electronics so make a habit of only loosely
wrapping my modified harness before picking it up and laying it on the
deck of the van being converted. Assuming that coolant, fuel, and air
intake is all connected, connect to the engine harness, make
connections to power and ignition in the black plastic junction box,
connect the T7A barrel connector in the junction box, connect the fuel
pump, battery/alternator connections, doublecheck your ground
connects, and prepare yourself for a big grin when she fires up.
Here's the diagrams i referred to:
Send an email to Tom Shiels with your vanagon year and he'll kindly
send you a copy of a diagram showing of the connections that are
required in the black plastic junction box.
Best of luck to you
Brent
