I am looking for diagrams for c100(bulkhead connector )and c207(underdash) for an 87 Firebird. I would buy a Helms manual if I could afford it, but money is tight this semester. I am slowly starting on an LS1 conversion and I am going to start with the wiring. This will be an ongoing project and I want to have everything ready when I find an engine/transmission. I appreciate any responses.

 

hey man, check out these and dig around a little-

There's some on the front of this site somewhere too. They may not be exact for your car but they'll get you what you need. If you get stuck on a particular wire send me a PM and I'll see if I can find it. I just got done doing this on my car. I think you have an electronic speedo, that makes things real easy.

 

Thanks. I couldn't find c207 in any of those, so I will keep looking.
