Here is a wiring diagram I created for my LQ4 swap using 0411 PCM into a 1986 IROC. It uses a Current Performance Wiring fuse block.

Hopefully this is useful for someone as it is very complete and has some special sensor information included.

Should note the MAF is not included in this diagram.

 

Nice drawing. I have it all in the books or on a spreadsheet, but this is a great all in one reference

 

Very nice!

 

Thanks, I wanted to have it all in one place. This is something I never did for my last swap and looking back over wiring notes scribbles in the manual sucks!

 

Wow. My hero. I got a 2002 F Body harness and computer I'm putting into my 1987 Trans Am. Car used to be TPI, now is getting an 5.3 installed (LS6 in take, F body acc, etc). Looks like just what I needed. Thank you!!!

 

What software did you use to produce this? If possible I would like to do the same for my '86 swap. My wiring is going to be a little different.

Its drawn in autocad.

 

Thanks for posting this. It's an excellent quick reference for troubleshooting my swap and for future swaps that I might do.

 

excellent, thanks. i'm gonna print it out to put in my binder. may try to color code it and laminate so i can use it in the shop without destroying it. did that with my 72 F-body's factory wiring diagram, and it sure comes in handy without ruining it.

 

Fantastic find here !

It appears to 17" x 11". My G-85 HP printer is 8.5 x 11", so I don't get it all. Any ideas on how to get a full-size copy?

Guess go to a print shop, have them access my file saved on C:, and make a copy.

 

It depends on what you open the file with, but you should be able to adjust the size in either the program you're viewing the PDF file in, or through the driver for the printer (sometimes you can also minimize the margins). Right click or go to, control panel, or "properties" from the top menu of the program you're viewing the file from.

I imagine it might be easiest to try printing on two 8.5x11 sheets vs. paying to have it printed. If you wanted to laminate it then taking the file to a print shop on a USB stick should work out.
