Looking for some help on Aim MXL with 2002 Mazda Miata. I have the MXL and EVO4 and GPS. I had a OBD but of course Mazda does not support this Miata to run that. I assume I will need after market wires? I am looking for RPM, Water temp, oil pressure and speed will come from the gps unit. Just need some help on what wires/connectors I will need. TIA.
