OK. Here is a picture of the plugs you need. The gray contains your power connections and the black is your speaker connections. The Metra part number of the connectors is 70-1770.
If you really wanted to, you could cut the connectors off and splice the wires directly. But please dont do that. Just go get the connectors (under $10) and do it right. Just splice the wires on the back of the CD player onto the connector wires of the same color then plug the connectors into the factory ones and BAM, your done.
The easiest thing for your key situation is to have a locksmith come out and cut you a new set of keys off of your ignition and door locks. If you just change out the ignition, you will need to change the door locks and trunk lock as well and that will cost more and be more of a pain than the locksmith. I had that done when I bought my 90 cause the seller had lost the keys and It cost me $80 for the whole shebang.
Excuse me now so I can go put my radio back in.
EDIT:
I just realized you had a 93. In 93 Ford changed the speaker connector. Yours looks like the older style but they are generally both 90 degree connectors, not straight like the one in your picture. I see a blue wire in your picture, that is the speaker connector. Make sure you get the kit for a 93 not the 1770, which is for 86-92. I think its a 1771 but dont quote me on that, I dont have my metra book handy. Also,Look behind where the radio goes on the floor and see if there is a small silver amp bolted to the floor. If there is, you will need to bypass it.
