Looking for some fuse box help.

Got a VDO new gauge in my dash pod. Works fine with 3 hours of faffing about. But, the illumination feed from fuse box (marked 58 on diagram below) I'm not sure what spade terminal to take this off the fuse box? Haynes fuse box Extract below too.

if you have a dashboard light dimmer I would advise stealing the power there. VDO usually uses regular bulbs (no LED) so you could dim it with the instrument lighting.

According to Haynes instrument dimmer isG8 spade ( got a pic if you need)
Grey/blue

Also worth noting you can pick up ignition 12v from G5 spade fused by no 18

Interested to know where you put the sender, is it a sump plug one?

His is an 1984 with the early fuse box.

Pick up the feed from the rear of the light switch from the dashboard illumination grey/blue wire.

That's where I have my sensor but I wonder if it reads right.
the oil there returns to sump from the oil, relief valve.
Probably not far off though.

Might go for a Prosport sandwich plate when I get round to getting the oil cooler back on. You can take the oil pressure and temp off the plate then. Haven't really looked into it yet though tbh.
