It says they're from an '05, so they would be real close to a 2003-6, the 2002 would be similar, but not the same due to the switch to DBW across the board on trucks in '03.

Can anyone locate the first Page of Fuse block under hood C1 that is posted above. There are three pages when 4 are needed. It is missing the A and the first of B. I am trying to do an LS swap and want to use this fuse block without reinventing the wheel. Snip and splice where I can to make things work.

Thank you in advance.

I'm finishing a Swap of a 5.3 out of a 2007 Silverado into a cobra kit car. The harness is aftermarket from bp Automotive but the last few wiring labels came off. I'm hoping these are close enough to get it done.

Can you send "Fuse Block - Underhood - C1" Gray!! A1 through B11. You are the only one online that matches my pin outs and you left off page 1.
Thank you for any help.

Why are you asking about Nissan wiring on a strictly GM forum?? Go to a Nissan forum if you REALLY want help. Otherwise you are a troll.

Default Ls harness

when transferring a bit of a harness from. A pcm that is color coded with red and blue plugs (donor) to harness and pcm with blue green green are pin out number the same?

For instance I have a drive by wire ls stand alone harness and I want to add the 4l60e harness to that configuration. And allow the factory pcm to be programed.

Default pdf

Is there any way anyone can send me this wiring harness info in a pdf file so I can open it while working on the harness, I don't have internet in the shop, I'd like to be able to save as a pdf, or print it out. Also I've put a 5.3 out of a 2003 suburban in a toyota build and believe this diagram will work for me, if anyone knows better any other suggestions? I'd like to be able to use original gauges, and probably have to add a few. Running the 5.3 with a turbo 400 and an np205 transfer case in a 94 toyota extra cab pickup.

Can you offer any assistance? I just acquired 5.3 out of a 2003 Suburban-drive by wire. I'm installing into a 71 c10. The harness is all there. Just need to label and identify all the gadgets, modules, sensors, switches, etc. Thx! Jay

Can anyone confirm If I’m missing some pins, more on the red side of the connector. 2001 Chevy Silverado 1500 2WHD 5.3 LS. I ran OBD 2 and I have about 40 codes all related to the harness. Camshaft, 4WHD, Knock sensors, all four H02S and a misfire. They all appear right after I delete codes. Original owner since dealer back in ‘04 first time running scan tool. Other than that she runs we’ll never noticed a difference lately.
