Content-Type: text/plain; format=flowed
Your '85 instrument cluster wiring harness cluster is missing wire #12. The
'86 and older Vanagons use this wire for the oil pressure alarm circuitry.
Run a ground to the #12 terminal of the harness, like Ken mentioned, and the
alarm should stop.
If you can't read the numbers on the harness this how the '85 wires are
ordered.
1 2 3 __ 5 6 7 8 9 10 11 __ 13 14
So you're missing #4 and #12. HTH -John
