I have a John Deere which had a briggs motor in it when I acquired it but it was blown. I put a Honda gxv530 engine in it but I can't figure out the wiring. The plugs match up but the wiring is different. Every wiring diagram I can find has different colors than mine. My engine is probably 10 years old but it was crated and never used, basically new. Do they make a John Deere Z225 A mower with a Honda GVX530 engine and if so can you buy a wiring harness for it ?
