Beginning with 1986 M/Y vehicles, the Lambda-sond preheating circuit is grounded at the right front fender.
This wiring change required new harnesses as follows:
for B230F P/N 1362594-2
B230FT 1362595-9
NOTE: The ground cable changes color within the harness from brown at the lambda-sond connector to black at the ground point.
