Refer to Handling ESD Sensitive Parts Notice in Cautions and Notices

Important: Twisted-pair wires provide an effective "shield" that helps protect sensitive electronic components from electrical interference. Depending on application, twisted-pair wires are used on wiring harnesses connecting the following components:

•	connector C200

•	connector C409

•	vehicle speed sensor (VSS)

In order to prevent electrical interference from degrading the performance of the connected components, you must maintain the proper specification when making any repairs to the twisted-pair wires shown :

•	The wires must be twisted a minimum of nine (9) turns per 30.5 cm (12 in) as measured anywhere along the length of the wires.

•	The outside diameter of the twisted wires must not exceed 6.0 mm 0.236 in).
