I'm trying to figure out how I can phrase this so that it will be taken in the helpful spirit that it is meant in rather than have anyone feel insulted... please remember that, like someone from the government, I'm here to help.
The only way I can think of to phrase this is that if you don't know enough about chasing down wiring to use a meter and the universal instructions to figure out how to wire it, then please, please enlist the help of someone who does.
The universal diagram, a meter and an understanding of how to run down wiring is really all you need to do this. You use to meter to identify which oven wires are connected to what (bake, broil, L1, L2, etc.), label them with tape and then use the universal diagram and the grey goo between your ears to figure it out.
But the ability to do that comes with experience and not a small amount of training in electronics troubleshooting or similar disciplines. If you don't have that, don't be shy about asking for help from someone who does. Just realize that this isn't the kind of thing that can be done via forums, email or over the phone. This is the kind of thing you need to get your paws into if you're going to figure it out.
