does any body have a picture of the batter cables for a 94 z28. im not sure if my harness is complete.

 

I can e-mail you a .pdf of the diagrams from the 94 factory shop manual if you want.

 

email me @ drlmel06@gmail.com
please . thank you

 

also do i have to remove the dash to get the harness out? i know there are 3-4 plugs under the dash thru the firewall.

 

The battery cables are not part of the engine wiring harness. They are stand-alone.

Are you asking about the main engine harness? If so, Shoebox has a photo, with clickable feature. It's for a 95, but is virtually identical to your 94:

1995 Z28 A4 Engine Harness

If you are not aware of Shoebox's website, try this link. It's the best resource for LT1 information on the internet, with tons of photos, wiring schematics, part numbers, system schematics, how-to's, etc.

Here is a place where you can download a whole 94 service manual (and some other stuff).

i wasnt sure if the battery cables were supposed to be part of the engine harness or not.
and shoe box website has been super helpful.

how do i get the harness removed from the fire wall?

 

Unplug the plugs under the dash on the passenger side, unbolt the pcm under the hood, pop the rubber grommet in the firewall behind the pcm loose , feed connectors through firewall
