Can anybody provide me with a grounds location schematic for a 1996 Chevy blazer ls?

 

Grounds for what? There are many, many grounds on a Blazer. I suggest you get a subscription to AlldataDIY. They have the factory wiring schematics and drawings of ground locations.

 

I'm looking for ground locations 102 and 104 for the interior lights. I'd love to get a subscription to alldata but money is tight right now. i use the free wiring diags from bbb industries website, they just dont tell you the locations of grounds or splice connectors.

 

G102 and G104 are at the back of the cylinder heads on a 2001, but 2001 has a BCM tied into the interior lights. Hope that helps. I'll try to remember to look it up for you on a 1996 when I get home. How much do you trust your BBB industries diags?

 

Ive honestly had success with it being accurate as far as the circuit design and wire colors. Like i said the downfall is they don't give you locations of grounds,connectors or connector pinouts, splice locations etc..... I did some poking on bbb for a 2001 blazer real quick and you're correct the interior lights are controlled by the bcm. Mine doesn't appear to have a bcm I'll have a look with an inspection mirror later to see if there are any wires grounding the back of the cylinder heads.

 

Here's G102 and G104. Year unknown. Good luck.
