Wiring Harness Question

[USMarine430]

Hey there folks - there is a part of the harness with 4 wires that starts on the backside of the engine behind and below the power steering pump/reservoir that has a small yellow tab on it with a hole punched through it.

The wire colors are Black, White, Pink and Lavender.

Intelligence has reported that it could potentially be
1) part of ABS
2) part of airbag deployment
3) part of wheel speed sensor

If anyone has access to a wiring schematic or manual, that would be awesome.

THANKS!!!!
