matrixisinyou Posted April 8, 2007 Report Share Posted April 8, 2007 Hi all, I found a post for 2007 toyota corolla regarding wiring locations for Speed Sensor & Reverse Signal, but I'm not sure if they are the same for '03 toyota matrix. Can someone please clarify? Greatly appreciated! Quote Link to post Share on other sites
