Austin thirdgen is not correct for what i need. I need an 88 firebird2.8v6 5speed wiring of c100 and c207, and one for an 87 camaro, 5.0 tpi auto, and nothing matches w/ austin thirdgen. any other good sites?

 

ATGO or AllData

Have you scrolled down to the bottom of the page for ATGO? Lots of direct scans from a service manual there

 

Autozone.com has a lot of wiring diagrams. You just have to register.

 

While Autozone does have wiring diagrams on their site, they are the generic ones like you'll find in the back of a Hayne manual.

This site:

http://www.austinthirdgen.org/index.php?pid=19

has the good ones from the GM shop manuals. Much more useful for troubleshooting complex problems.

 

Thanks for posting that site. I didn't know about it.

 

I don't think that there are many (if any) differences in the c100 and c207 connectors - I think if you just pick the year closest to yours, you'll see what you need in the Austin diagrams. Like the 1988, pick the 1987 diagram and in it are differences for different VIN codes (8th digit) - you don't want the 1989 year because there would be newer changes - make sense?

Just because it doesn't have YOUR year listed doesn't mean it won't work as a diagram.

 

my main thing is Ive found on Mitchells at my shop is that firebirds use the G4 on the c100 to feed the fuel pump, and that camaros use d 0n the c207. I know that c100 between my 88 2.8 firebird and the 87 camaro 5.7TPI were much different

 

can anyone validate this?

 

Its a difference in the years, not brand

 

whoops, you are correct, thats how Austinthirdgen has it. i Wonder if this change was made in 88?

 

I have a Chilton's manual, an account on Autozone, and I just looked at the diagrams on that link. All three give the exact same diagrams. They are definitely lacking some circuits.

I've had subscriptions on alldatadyi.com and currently have one for my 01 TA but I don't want to spend the $25 for my 89 if the diagrams are no better. Does anyone know if the alldata diagrams are better for third gens than the generic ones from the sources listed above?


Edit: silly me I didn't scroll all the way down on ATGO, I see they have other diagrams that aren't in my Chilton's manual or on Autozone's site, not as many as I would expect must be out there though.
