That is for the "dynamic oil pressure warning system". 86+ has 2 oil
pressure switches and  a logic board inside the speedo that they connect
to. If you use a blue foil with the factory extra connector on it you
need to use the logic board too or you won't have any oil pressure
warning at all. You can jumper the 86+ foil so it works like the 85 foil
and then does not need the logic board. There is a empty place for
another resistor on the 86+ foil and putting that resistor in converts
it to an 85 foil as far as the oil pressure light goes. You need to
leave the 6 pin connector unplugged when using the resistor.
