nope.

plug it in and fire away. don't forget to disconnect the batter or unplug the 15 fuese before swapping.

just for precautionary purpose. either unplug the fuse for the ecm or unbolt the battery so no current to flow thru. this is to prevent voltage that might spike into the ecm. most of the time you can just unplug the old one and just plug the new one in, but i rather be safe than sorry. good condition ecm/pcm is harder to get by day after day these days for 94-95 v8.

i actually got one from our local pick-n-pull and it cost me nothing. just slipped it into my toolbag and away we went. also did the same with injectors for testing and the edis module. all free. anyway, there are about five or six or even more of these 4.6l lx at the pick-n-pull so i have my choices in parts.
