M&H wiring harness's disappointed -Update - 07/07/09 10:57 PM
I guess I expected better, since this is supposed to be the best. I ordered all new harnesses for my 71 B project. I just checked two of them tonight and both are not correct when compared to my originals and the wiring diagram. I'm I expecting too much. The harnesess are still functional but in a few years when and if i have to troubleshoot they won't agree with the book.
1. 2 speed wiper motor. In the picture the red and brown wires are switched. The two wires going to the resistor are brown instead of red. And the harness is 3 inches longer than my original. Now the red and brown wire carry properly at the other end so it should work OK.
2. B/U lamp harness. They have a violet wire instead of black. Again this is compared to my originals and the diagrams.
I'm afraid to check the other more complicated ones. I'm gonna call them tomorrow to see what they say. Anyone else notice this???

M&H makes the most accurate and likely the most reliable reproduction harnesses on the market. No, they are not perfect. Sometimes thier mistakes can be fixed by modifying them to match your original harnesses.
If you expect perfection you'll need to find NOS harnesses, not the easiest task these days, in some cases it's simply impossible as they don't exist. Some will say that NOS are no better than used, but in my experieince I have never found a bad one that's been in dry storage in original packaging.

"2 speed wiper motor. In the picture the blue and brown wires are switched."
Actually it is the red and the brown wires that are reversed. Make sure you correct that.
Concerning the brown wires versus the red. Brown wires were used until late 70s and then they used red.
I am sure M&H only offers one type just to save costs.

"Actually it is the red and the brown wires that are reversed"
Jules - Correct, my mistake in colours, I will correct. Didn't know they actually switched colours when its basically the same part. I will still call them and see what they offer as an explanation.
Snoopy, that's the same diagram I'm looking at and my old part matches that. Thanks
As always, live and learn when playing with this stuff. Thanks, now on to the other harnesses.

I appreciate you posting this. I didn't even think to look at the wiring, I just looked at the connectors. I'll double check mine as well.

Guys, make sure you check any harness.
A friend just got one for his 71 RR clone, and they had some bad stuff mixed up! If it had not been checked, it would have caused bad things. I'd never heard of such issues, and would not have thought of having to do this, but now I will!
I don't know who did his, so this is not directed to any company in particular.

Funny how there was a post a while back where people were bashing Evans wiring and a few guys were talking about how great M&H was. Not saying there bad, but as said before every one can have a slip up now and then. Sorry to hear about your wiring. At least you had the brains to check it out first. The stuff I got from Evans was good and it was pretty inexpensive, so I will keep returning the business till they change my mind.

Some will say that NOS are no better than used, but in my experieince I have never found a bad one that's been in dry storage in original packaging.
I did have a 71 B body NOS dash harness in the package, that was found after install to have been "assembled/wired" incorrectly by the "vendor"....it was later corrected using a factory manual......NOS isn't perfect either, M&H makes some rather nice harnesses, and I sure they make mistakes as well,.....I'd rather trust a M&H "new" harness, even if it needs correction, than an old 30-40 year old harness/wiring,....seen too many people lose cars to electrical fires over the years than I care to remember

So have I, which is why I am an advocate of replacing all original used wiring when doing a restoration even if it "appears" to be in mint used condition, but I've never seen a newly installed NOS harness fail or cause any problems, only old original used ones.
Personally I don't think you'll have anymore issues with an unused NOS harness than you would with a brand new reproduction (regardless of the vendor). It's a non issue anyway since finding complete nose to tail NOS wire harnesses set these days is almost an impossibility.

I'd call M&H directly (not Year One) and speak with Tom. He is very passionate about the products, a real car guy, and when I had questions on their harnesses I bought a few years ago for my 69 R/T he was top-notch to speak to.
He seemed very interested to know if there was any issue with quality or accuracy.

Oh yeah... and then come back and report on your experience, GOOD or BAD!

Any updates after that phone call?

I'm calling next week, I just checked my engine harness and backup light harness yesterday. So now I have all of my data ready. Later

when a few years ago i bought a tach harness for my a12 superbee,when it came in it was too short, it was for the standard nonralleye dash, but the ralleye dash tach is on the far left and standard dash is on far right,
M & H made it right, and sent out a new one right away, they are good guys.

I could not agree more. If there was a production problem, he will want to know. Let us know what he says.
Good luck,
Randy

Norm, you need to speak to TOM! He has helped me out with a few wiring issues. He's a GOOD GUY!

Well, thanks everyone for giving me Tom's name at M&H. We spoke today for 1.5 hours and he took the time to go over my findings one by one. He also offered to make things right on each one of those findings. What a great experience, and he was very interested and curious on why the differences occured.
How it was left is that I send him my originals and the new harnesses with a note and he will look after getting the new ones back to me.
Some of the differences was due to a manufacturing hickup, some the harness agreed with the engineering drawings but as you all know in the Mopar world things aren't always as they seem and some he must investigate more.
In case you read this Tom, thanks again, it was a learning experience.

I knew Tom or Robert would come through.
We all make mistakes, the difference is when one finds solutions and
offers great customer service to achieve a common goal.
M&H rocks.

If M & H "rocks" so much then they would sell their wire harness's somewhere other then Year One..

Probably cause Year One has the exclusive rights with them since they backed the main harness reproduction. Just a thought.

Alan, If you were the one that was responsible for all the costs of having a product produced, wouldn't you expect to have exclusive right to sell it?
If Year One hadn't stepped up and paid the production costs for the Mopar harness components used in the M&H harnesses, you would be complaining about the lack of quality wiring harnesses available to the Mopar community.
I am sure that Tom at M&H would love to sell his harnesses to anyone that wanted one, but can't because they are being produced under contract to Year One.

More cost for a quality reproduction is inconsequential compared to a car fire that destroys a vehicle.

Information I was unaware of.... 
It would be nice if M&H could sell their own product.

What they CAN do is custom make any harness for you that isn't being offered by year one. This is usually the accessory harnesses. I've had them make a cruise control harness for my 70 E body. I've also heard of them making the 4 speed reverse light wiring, and power window wiring. They'd probably also custom make a harness for you based on the year one harness if you needed some special modification. Tom is the man to deal with.

That's correct, they are making me a 4 speed reverse light harness and they also offered to look and freshen up my taillight housing. On a 71 B body the wiring is integrated with the housings.

I planning on replacing the wiring harnesses in my '69 Road Runner. I was thinking about using Evans wiring harnesses. Has any one had a good or bad experiences with their products?
Thanks,

I can only say good things about Bill and Rose. I have been using their harnesses for years with no problems.
