for cheaper and easier than the toyota unit, why dont you look into getting an msd or similar? i have saved a writeup from pirate about that, heck, for the gm conversion although i have never heard of it, it still might help you out
since pirate started charging for you to search by buying some star, its pretty much become useless for all the freeloaders liek me on it
