Yeah, just one hole on each side.
In other news I got the truck running. I think my buddy tried hooking the ECM ground up to the positive side of the battery and that's why it wouldn't start? Like I said... wires clipped off everywhere and twisted together, I can see why it would be an exercise in futility for someone who doesn't know what they're looking at.
Allegedly there is a significant battery drain that I will be investigating, could be from wires shoved into fuse holders, or who knows what. I also discovered that it has almost no brakes, the driver's door needs hinges and a striker post real bad, and there's a rather large water leak happening on the driver's side floor.
