Logic board replacement instructions

IMac G5 10.4.11-1.8 GHz

I have purchased a replacement 661-3611 logic board and need instructions on how to install. I found a guide for a different model ( the A1058) but don't know how close they are and don't want to take any risk. I also purchased the thermal paste.

Is this a good question?

Thanks a million Mayer. I had already downloaded this manuel but feared it was not the right one. The A1058 threw me off??? Hoping all goes well with the installation.


Actually I just compared it to the one I had downloaded prior--same A1058 but different manuel. Grateful to have two references now. THANKS AGAIN.
