65 'Cuda 273 No dash lights or gauges

Hi,
I have just bought a '65 Barracuda Commando 4 speed. Thing is it has no dash functions, the wiring doesn't appear to have been tampered with. Speedo is probably down to the cable, but i will do that when i do the drive seal in the gearbox. I just wanna see if i can get the other functions all working correctly. I haven't got the car yet i went to look last night and did a deal. But I wondered if with the expertese on here someone could give me a clue as to what might be the problem?
Thanks,
Fraser
