i'd still say it's worth asking your dealer service guys to pull out the electrical diagram & verify by the last 8 of your VIN which holes of the fuse block have your clutch safety switch wire.






found this online. The v6 is still in the truck so, The wire from the pcm should still be there. I’m guessing I just need to run a wire from the clutch safety switch to the white firewall fuse block connector

shouldn't be no need to run lines... it literally just goes from one hole to the next in the bottom side of the engine harness fuse block.

yeah I found those pictures of yours two nights ago and went out to check and I’m pretty sure there was a green/white wire in F11. I could’ve been reading it wrong but I’ll check again when I get back into town

installing an engine/harness for a 2001 into my 99, i only had to swap the black engine-harness section of the fuse block; the rest stayed.
crossing configuration boundaries from early-NBS to late-NBS, i couldn't tell you for sure.

Right. I did the opposite. The v6 stayed in but swapped out the dash harness

Do you mean the unions connecting the braided stainless lines?
The part numbers for all the fuel lines and connectors are at the beginning of this thread.


This was a test fit for length to mark the hard fuel lines for the cut.
