Cab bought off Craig's List

[1mk2]

I bought a cab off someone one on Craig's list, it is not the newer ones that are all metal but it has soft sided doors. Of course he didn't have a manual and I can't find any serial numbers or model numbers. I think I can figure out the mounting but how do you connect the wiring for lights and wiper's? If anyone is familiar with this or maybe you have one yourself. Would appreciate any help you could give.
I will try to take a picture of the new grasshopper I bought as soon as I can. It is a model 727k EFI. Rainy weather now.
