Extending and connecting O2 sensors

One of the steps to prepare the wiring for the coyote is to modify the O2 sensor wires. The control pack wiring comes with a less than optimal setup – the wires are bundled much too close together to stretch across the massive wingspan of the coyote and equal length headers! Here’s a before and after pic of the harness.

My son loves showing off his soldering skills and it worked great! The driver side was about 20-24 inches too short and we extended the wiring to match up perfectly. Note – never modify the O2 pigtail itself, but the wires leading to that pigtail are modifiable.
