This kit is made to upgrade your factory positive and negative wires to increase your cars electrical system. By increasing the size of the wire, it will raise the alternators output voltage which will improve everything's performance that uses the 12 volt system. For example, ignition, steering, stereo, headlights, etc. When we installed this on our shop Sonic it bumped the voltage .3, other people have reported more. We are not tricking the alternator to put out more voltage, we are just allowing the full voltage from the voltage regulator to make it to the fuse panel and battery. Whatever output voltage you have must have a better ground as well, so we include 2 upgraded ground wires as well.

The Cruze comes with 1 less wire than the Sonic.

Note: The Sonic uses a battery current wire sensor that attaches just below the battery on the negative terminal. The main ground wire going to the battery must be routed through this sensor (looks like a big hook).

Pretty easy install with some help of youtube

lights seem to be brighter and the car doesnt sag when the ac is on anymore

Before installing my 45,000 mile 2019 RS Sonic Sedan-ly would show 12.8-13.0 volts at idle (775 rpm) with nothing but the AC on. After installation of both the ZZP coil and 4 wire kit (on top of original wires because you can NEVER have too much capacity) at idle with doors open, hood and trunk open, fog lights and low beams on, AC on high and stock radio playing Stevie Ray Vaughan at full volume, 13.2 volts. With nothing on at idle but the AC on high, 14.8-15 volts. I ordered both the ZZP coil and wire kit on 07/03/2022, they arrived priority shipping on 07/08/2022 and I installed on 07/09/2022. After reading the pdf instructions and comparing the wires to the pictures and to how my car was, installation for both was in less than an hour from start to finish. Because I used both factory wires and the ZZP kit I needed to tweak the connectors (bend) so both wires would fit and tighten properly. The only differences I encountered was the nut on the fusible link #2A was 12 mm instead of 13 mm. The only other difference was where the engine ground connected, #1D. On my 2019 RS sedan, the engine lift and #1D are reversed, but it wasn't an issue because all the cables were long enough for the unexpected and proper routing. The ends and connectors are well done and well protected and I expect to have ZERO issues in the future. After installing the coil pack I really wished I had bought the coil cover which I will include with my next order.
