Re: 5.3 into 72

What fuse/ relay center did you use.? On my 2005 5.3 , I used under hood fuse box for connecting stock harness. Unfortunately the tranny got its power from the interior fuse center on that model truck. Found out the hard way it wouldn't shift. Did some digging to find that out. God luck. Jim
