This harness is far better than the OEM version. I made the first one for my own 968. The main alt cable is 6-gauge tin-plated aircraft cable with Teflon (FEP) insulation. The exciter and solenoid wires are XLPE-insulated and they are soldered and crimped at terminations. This is a direct replacement.
