turning over

[misty]

Hi all hope you are well
I have the electrics nearly finished now,so much so ,that the engine is now turning over but not yet firing up. What i need to know is the engine is a 2lt pinto with R1 carbs on,fuel pipe is on but a little nervous about putting petrol in and trying to start the car.On the carbs there is a little electric plug would anyone know what this is for and where it connects to or maybe not needed if anyone has the same setup if they could send me some pics to my email addresss that would be great
