Vdo wiring , live feed

Which live feed is best for connecting to the 3 vdo gauges. I'm going to be using a vdo oil temp gauge, vdo oil pressure gauge and vdo volt gauge.

I've seen suggestions for using G2, G3 or G5 which are on the back of the CE1 fusebox.

Which G spade terminal would people recommend to use for the live feed to run these gauges. This  is on a 1983 mk 1 Jetta 1.6 gl with CE1 fuse box blade fuses.

Lastly what size connector and plastic cover will I need to fit onto the G spade terminal and also trying to find the small female connectors that fit onto the bulb assembly on each vdo gauge.

I've done some searching on the forum and om happy with the rest of the wiring required.

Thank you in advance
