And one more, where does the negative battery cable correctly hook up to the engine? (350/300hp - Quad., no air).

I always thought it was the the thermostat bolt, but my engine guy was skeptical.

Hey one more question based on your pic, there's a small white tab that's pushed through the alternator bracket from the bottom. What's that holding? (Or am I seeing things?)

That's the wire that goes to the back of the alternator. The tab is embedded in the wiring harness.

oneZ11.....Do you have an AIM?   If not, then you need to get one and examine it front to back until you nearly know it by heart.  That is the first thing I did and it in turn answered numerous questions that I had about the Camaro assembly process.

I agree w/Jerry!

I'm not sure how much detail you are after here, but just in case, this "Strap" was added on 1-23-69...hopefully you can begin to understand how important it is to have the AIM.

Thanks for the info. Don't laugh, but "AIM" - is that short for the Assembly Manual?

Assembly Instruction Manual. Here are a few. It should be like the first one on the list...

IZRSSS – Any idea where to get those wiring clips you pointed out in the pics? I checked with Classic Muscle and could not find. Also, one looks white in color.

I found this on Rick's. Is this the one on the fender?

Thx.

A good friend saved these clips (pics) from when he worked for GM. He kept them wanting to use them on his own project. Unfortunately he had to sell his Camaro. I used the ones that worked best for me, neither of which are like the originals.

The clip in your pic is obviously a re-pop but should work fine for the fender. The problem is, the original was not offset (look at pic) but how many people actually know this. This same offset will not work for the alternator bracket. by the time you attach it to the harness and tape it, it will be too bulky to penetrate/seat properly. And, no idea on where to get the clips. I checked for several days and the only one I could come up with is the one in your pic. If you find out, let me know.

As for the color, both of them should be white/off-white. But again, sure beats the heck out of buying the entire harness, and again...who really knows  Wink.

Awesome, thanks for the legwork and the photos. I'll let you know if I find a accurate repro – not a huge priority right now...

That offset repro clip is used in the middle of the front lighting harness under the rad support.  I haven't found a source for the other clips either.  Probably the best bet is some used harness and take them out.

This seems to be all a person can do & there should be a lot of them out there in junk yards or maybe at swap meets. Just be carefull, I'm sure their awfully brittle.

Hey Marty, I don't see the clip on the alternator bracket. Does this strap take place of the clip? I thought I read somewhere the clip was discontinued and replaced with a strap. Is this the case?

Daniel - Unfortunately all I have to go on is the AIM and its usually the safest bet. If you look at AIM C48 - A2 both are used in unison. Also, the Revision Record only states it was added. Doesn't say anything about a replacement. I guess the thing to remember is both the clip & strap (or some sort of hook) went into effect on 1-23-69. Hope this helps.

I'm curious to know what #11 looks like installed. Does anyone have a pic they can share?

#11 isn't a hook, its a plastic strap/tie wrap. It secures the battery cable and alternator cable harness together. On AC cars such as yours it may have been routed differently,as pictured.

I guess a strap makes sense as long as the negative cable is attached to the swivel clip at the Alternator bracket. Otherwise it would be worthless. As my post stated, I was just interested in seeing a pic as it applies to the AIM. No need now that I know its a strap (knuckle head...it says it right on the AIM  Embarrassed).

BTW #11 wouldn't apply to me...my car is a 12A build. Although I like this set up much better (strap to light harness & neg-cable).

Here is my 9B of 68 built L34. There was always a clip attaching the alternator harness to the alt bracket. Not sure what you are searching for, but below is a picture my L34 survivor. I have higher resolution just PM me.

Steve - this thread has changed topic about 3/4 times... sorry if you've been mislead. I agree with you 100% with regards to the negative cable as it relates to the swivel clip on the alternator bracket. My question has nothing to do with that. I was just curious to know what #11 was/is per AIM C48 - A2. When I first looked at it, it looked like it was attached to the alternator itself. You answered my question when you mentioned it was nothing more than a strap. I over looked the description at the top of the AIM pg.

The reason it doesn't apply to me is because #11 was added on 1-23-69 (per Revision Record at the bottom right corner of the AIM pg.). Any cars built prior to this date did not have them. This is why I stated it does not apply to my 12A built car. Hope this clears things up  Wink.

That doesn't mean there wasn't something there before that this strip replaced. And you need to read http://www.camaros.org/AIM.shtml - that date has nothing to do when it was implemented on the production line.

I'm not sure how anyone keeps up with all this stuff. Thanks, I found it towards the bottom of your link. If I read this correctly, just about any 69 can have this strap. In that case I think I'll add it. Seems like a good idea.

The date of a revision almost never indicates the date the change actually took place on the line; it just shows when the sheet was revised, which could have been well ahead of or well after the part change occurred in production at the assembly plant.
