    The dash idiot lights are flickering and the oil pressure sending unit
    wire has lost all of its insulation . I would like to reroute this
    wiring away from under the crank pully . I have misplaced my Haynes
    manual . Could someone please identify which corresponding wires
    at the gray connector is the alternator "field " wire and the oil
    pressure sending unit wire ? -thanks

    The red wire is D+/61 at the alternator.
    The black wire is the OPS
    The yellow wire is the coolant temp sender for the gauge
    The blue/yellow wire goes to the starter

    The 'Wrench is right, oil pressure sender wire is black, harnesses for
    '85-87 cars is $318 at ipd. Green op wires are found on 240Ts only. You
    might also try Dave Barton's site for a good used replacement harness. The
    under engine wires just show the damage first, you will find other areas in
    the engine compartment where the insulation flakes off over time and
    exposure to heat and oil, fix them all at once for ~$160

    I've gotten a couple from him, good quality and half the dealer cost.

    Even on a turbo the OPS wire is black. The green wire goes to the Oil
    pressure gauge through a separate harness.

    Sorry Bob, got 2 turbos sitting right outside and the green gauge wire goes
    through the main harness with the black oil light wire, alt' exciter and
    heavy B+ cable. I should have been clearer but I was addressing Brick_0's
    innaccurate information regarding the green wire in a NA 240. The
    accessory gauges for non turbos had a seperate harness with a green wire but
    a stock 240 has no green wire associated with oil pressure.. The original
    poster has an '85 NA wih a black oil light only setup.
