Thank You! now I need the connectors

I'm not sure where to get connectors alone (would like to know that as well). I do know American Autowire sells a complete re-wire kit with the connectors. It is kinda pricey though but you do get everything. http://www.americanautowire.com/view-product/1973-1982-chevy-truck/

Went with a EZwire Kit, they run $185.00

Nice! Does that come with the connections?

No its a general SBC Chevy universal Wiring , I looked at that kit but at $700 bucks vs $200 , figured connectors would not cost $500, what nice about the Auto Wire kit it should save time replacing the old wiring, but again just to be PIA, I thinking of up grading the connectors since 80% of my Blazer is modified inside and out, I was looking into the Silicone sealing plug Connectors, So I was wanting to know on the connectors how many pins per connector required.

That's a good idea! Might have to keep that in mind when I do mine.

Man I am so glad I decided to do this, The crap you find as your re do someone else s work, I have a 74 Blaze with 77 -81 front clip and 81-85 wiring, don't ask me why, but trying to replace items to be in the year category 77-81 (LMC is ready to kick my azz) for all the items I buy then return.

That is a wide year range! How are the seal-all connectors working for you?

Just an FYI, those are simply GM Weatherpack connectors, and you can *probably* get all the pieces quite a bit cheaper over at mouser.com if you are just doing the connectors. Of course, you can find proper color coded primary wire pretty cheap too, so building your own harnesses isn't that tough.

If anyone wants me to do the work, I can at least post a link to the Delphi catalog that has the part numbers for the Weatherpacks. Then its a simple matter of dropping those part numbers into mouser and ordering them.

Weatherpacks are bulky compared to other Delphi connectors out there, but they can handle a fair bit of current, and are easy to deal with. I've used them for my trucks electric fans, solar panel setups, etc.

This is a great source for when I start mine, should save some bucks too

Unsolicited response to myself, but here is the Delphi Weatherpack catalog with all the part numbers which can just be dumped into mouser: http://catalog.delphi.com/connectors/assets/product_brochure/Weather_Pack.pdf Most of the terminals and seals are so cheap, if I'm not sure, I just buy a few and see what shows up. If they are right, they let me get what I need done with no or few spares, if they are wrong, I just have spares for another project.

I'd recommend/advise there is no way to do it otherwise, than buy one of the somewhat cheap crimpers ($20) and the tool for depinning the weatherpacks. Those tools, with new primary wire, will have you not using your soldering gun/crimp joints anymore.
