ECM for a 94 4 banger.

The broadcast code (4 letters BKCP) is for the chip inside it which you would swap into your new ECM because it contains all the vehicle specific coding.

You can get those on ebay also. For more than the ECM.

Whoa, there cowboy. Those old ECM's are PROM (read only). You need a 98 PCM or newer that is an EEPROM to start being able to do your own programming. Unless you have a pile of blank chips and a chip burner.

I don't believe so, but you definitely want the battery disconnected before doing any connecting of anything to an ECM.
There are a bunch of little tips like touching both battery cables together after removing from the battery to discharge any static, but I've never done them and haven't blown one yet.
