Wiring for 4.0 to 5.0 conversion

[explorerofdeath]

I'm doing a 5.0 conversion and think I have read about an auto manual that you buy one for your X and one from the donor vehicle and it has more detail than a Chilton's or Haynes manual to help with the wiring. Anyone know the name of any?

Thanks

Helms maybe?

That's exactly what I was trying to think of, but just couldn't remember, Thanks.
