no fuel or water temp gauge tried lots but need some assistance as going to Le Mans in the morning!

Hi all again. Sorry to start a new thread.
Car passed its mot yesterday so almost ready to go.
2 things though!
No petrol or temp gauge
The wires show no breaks
The senders appear to be fine.
Tried some gauges from an old set of clocks
leaves me to thing the circuit on the back of the dash is bust!
is there any way of hard wiring the gauges with seperate wiring?
Any help would be much appreciated!

jump a wire between the purple/black and brown wires on level sender, gauge should go to full. with dash temp bridge the red/yellow to brown if its a 2 pin plug, if its just the single wire spade earth it to the head and as above gauge should go to full.

if not start at the clock plug, disconnect it and check all the wirign is good and the pins in socket are straight, bend if a bit flat. check the contact pads on the blue pcb foil too make sure not worn away or dirty.

good tip on here was to remove the plug surround then pack out the pcb with a bit of card to help the contacts
