That's also one of the things I'm confused about. Did you need the fuse block from the donor truck? Or how will I need to incorporate the 5.3 harness into the '95 fuse block if at all? Sorry for all the questions I just want to make sure I'm 100% prepared before diving in!
Oh your fine, ask away. Get all the info you can.
So you don't need the donor trucks battery Junction box/Fuse box... Unless your wanting to use it.
It's helpfull to remove the connectors from the donors fuse block (as opposed to cutting all the wires at once) so cut wires and keep track as you strip down/label the donor harness per lt1swap.com instructions. (painters tape and a marker to label wires works good)
Weather you use the little fuse block and relays like the lt1swap.com instructons use or go with another fuse block/panel it's going to be independent from the 95 fuse block.
Basically when the harness Is all striped of Un needed wires your going to have orange wires that need batt + (2 I think) and all the pink wires will be 12v switched(plus a Few others that need to be 12v switched) .
On my setup I found a empty spot on my 91 fuse box that was hot when the key was turned to run and crank.. So I ran a wire from there to my constant duty solenoid that feeds my new fuse panel. Or it can feed a relay if you use that little fuse block from lt1swap.com. That's about as integrated as the 2 get. You can find a power source in the 95 fuse box for your new obd2 connector also.
