Use a fuel injector.

On the top of all the injectors you will see two wires. All the injectors share 1 wire that has the same color, and the other wire is differnt in color on all the injectors. Tap into the odd wire on any 1 injector. This usally is a good tach source on most cars. Let me know how you make out!!!

Just because it's fuel injected doesn't mean it doesn't have a distributor. If you find that the fuel injector route is easier and works then by all means go for it. If it's not working for you I would take a look for the distributor option.
