Big 3 upgrade

[Z71Sierra]

I've searched for info on the big 3 upgrade on both this site as well as fsc and cannot find any threads about it. If there is one somewhere please post the link, otherwise:

I am looking for the what and how to on the big 3 upgrade for my 94 gmc suburban with the 5.7.

Thanks,
Ryan

ffs I just found a bunch of threads.

Searching for any variation of big 3 doesn't turn up anything. Searching for "electrical upgrade" pulls up all the results.

please delete thread.
