Recommended a new wiring harness

Gonna start reassembly of the 67 hopefully over the winter. Who makes the most plug and play harness for a 67?

Also who tends to have the best prices these days for parts? Thanks

I'd say either AAC or M&H, I've bought from both and very high quality IMO, if you're going to use an HEI dist be sure to add it when you order or you'll get one for points, well that's for the engine harness anyway, if you're converting to a console don't forget the wire for that or back up light jumpers, sucks when you forget to order and find you're missing 1 little piece of the puzzle then the shipping cost is usually as much as the part lol
 
When I was going thru my car I didn't replace every harness. I basically replaced any harness that ran outside of the interior and was affected by heat or the outside elements, like engine compartment harnesses and rear light harness. I only wanted plug and play harnesses but did opt for harnesses that had already been altered if you were running an HEI instead of a points distributor or a alternator that ran an internal voltage regulator. When I did mine I ordered directly from AAW because prices weren't any cheaper if you ordered from a regular parts vendor. Back when I ordered my harnesses we weren't going thru times like were going thru now and the delivery was quick because they had everything in stock. Their harnesses are spot on with the correct connectors being used and the correct location of clips that are used to hold the harnesses to the body. I would recommend AAW's harnesses to anyone and another thing you can buy different terminals. plastic connectors, etc. separately if needed. You can try Summit to see if their prices are cheaper

I didn't replace all of mine either. I found a used OEM for the dash and bought AAW harnesss for under the hood (72's take 2 IIRC), the rest are factory.
 
thanks for the replies. I hear AAW and M&H a lot on the threads. If you get a harness specific to your vehicle is there and splicing needed? Are the terminal connectors already attached? I seem to remember people talking about having to buy a specific set of crimpers.

Thanks

You can use ordinary crimpers, but I crimped and soldered them. Most already had the plugs on the ends but the upgrade one I bought I did have to change some connectors on the ends to match what I had (like steering column wiring).
 
Can you buy the specialty connectors that these old cars need? I’d hate to spend $600 for a new harness and still be using 54 year old brittle plastic.

Thanks and sorry if these are stupid questions.
 
Like Jon said it was mostly all plug and play, but since I made a couple of changes (not the stock steering column for the car) I made those changes, but it came with stock connectors.
 
If you buy AAW's factory fit harnesses they will be just like the originals with all the plastic connectors already installed. There's is no crimping necessary with the factory fit harnesses. I put a aftermarket billet gauge insert in my car to replace the sweep speedometer set-up. I used Autometer Gauges in it and found out AAW actually made a special harness for it to go along with the Autometer Gauges that I had picked to put into the insert. With this you did have to splice that harness into the sweep dash harness but you can do it neatly and not make it look like a mess. I hate seeing a harness that looks like a rats nest especially in an engine compartment with this and that spliced into it that's why I went with the factory fit harnesses that were made to work with a HEI distributor and a alternator that has the internal voltage regulator in it. When you come to dash harnesses you just can't get away from splicing radio speaker connections into them unless your using the same speakers that came from the factory in it. I knew I would run into that problem when working with the interior dash harness so I bought terminals from AAW that I could use in that process. You can buy a set of their crimpers or pick up a set on Ebay that will do the same thing for a quarter of the price seeing you won't be having to crimp every terminal like you would if you buy their custom fit harnesses.. Go on AAW's website and download there catalogs and it will show you the different terminals and connector ends you can buy from them and just match them up with what you have now. I'm including there website that you can look thru and a picture of the cluster I put in my car. http://www.americanautowire.com/

Mine looks almost identical to that one.

Yeah, it worked really good for what I wanted it for and I have used them since then. I could maybe see buying the better crimpers if you were making the harnesses up from scratch and had a lot of crimps to do.

I bought mine from Napa and mine are pretty beefy. Personally I like to solder my connections as well and some would consider it overkill, but when I make those connections, I never have to go back and look at it again.
 
American Autowire is the best in the business. I use them exclusively on all customer cars and my own. I'm also a dealer for them and they are local to me (30 minutes away). They have factory harnesses built off the original Packard blueprints as well as the Classic Update system which is for more modified cars.
 
I did the AAW when we were shut down with Covid. I went with the 20 circuit upgrade harness and don't regret it at all. I also installed the Dakota Digital RTX cluster at the same time as well as the dash trim, radio bezel and glove box bezel all at the same time. Stuck in a retro sound Hermosa radio and the complete job took me 4 months bumper to bumper including new front turn signal lamps/bezels etc. I am a bit crippled so it was a challenge doing it. Got new carpet at the same time.
