I used ECU battery and ECU ground. Check your pinouts to see if that's feasible. Keep in mind you must use constant power (that doesn't die when you key off). That way it can keep your tank data. You can also find a wiring diagram for your radio. Radios generally have a constant-on power lead in order to keep station presets, etc. Hope that helps.
