Hey guys I did some searching and cant find anything on this! I upgraded to the jb4 but I still have my jb3 1.4 pinout harness, can anyone link me to a instructions on how to convert the jb3 pinout harness into the jb4 pinout harness. I seen jb3 pnp to jb4 pnp but not from jb3 pinout to jb4 pinout. Can someone please help me out. I would really appreciate it!
