I've got three sets of SPA dual gauges coming.

*Oil pressure/ Oil temp dual gauge
*Boost pressure/ Water Temp dual gauge
*Fuel pressure/ Volts dual gauge

They come with all sensors, but does anyone know if I will need any additional bits/fitting kits etc? Or any bits that I might not necessarily need but will make the job easier like extra wire etc? Any fitting guides for these gauges around as I've searched on here and there is a good guide but not specific to these gauges. Any help appreciated guys

Thanks Aaron
