| | Posted: Fri Jun 03, 2016 12:47 pm Post subject: 1969 Ford 4000 Diesel Wiring Harness | So I just bought this tractor. In trying to figure out why the lights don't work, I learned that some dear soul has cut the wiring harness. I've been trying to determine which wiring harness I need since this tractor was made in the UK and the FoMoCo manual says that Series A & B tractors (somewhere & Bedlington, UK) use a 1 piece harness. C series tractors (US made) use a 2-piece harness. After a couple days of banging my head online, I called New Holland. I gave them my serial number & unit number. They told me that I needed the following harness: 81830069 D3NN14A103H. Description:
One New Aftermarket Replacement Front Wiring Harness that fits New Holland Tractor Models 2000, 3000, 3400, 3500, 3550, 3600, 4000, 4400, 4410, 4140, 4500, 5340, 3150. Replaces Part Numbers D3NN14A103H, 81830069. NC
That implies that there's also a rear wiring harness..
Oh yeah. They had one in Indiana (I'm in SC) and the price was $473. I just looked it up on Amazon - $68. CAVEAT EMPTOR (Buyer beware)!
Anyway, I'm thinking that I'll just splice those wires back in. Maybe cut since the lights were all corroded and maybe were shorting to ground.

Does your tractor still have the horn and turn signals that the Euro models had?
If not just buy a wiring harness for a 3000 diesel. They are not color coded the same but are 2 piece, cover the lighting, charging, starting, gauge cluster and thermostart circuits. Easy to install.
The reason I suggest a 3000 is because there are two different Ford 4000s - the early 4 cylinder model and the 3 cylinder model like you have and some sellers don't know the difference.
The 3000 harness is identical to the 3 cyl 4000.

Just a horn button in the dash. I don't care about a horn or turn signals. Lights are necessary, IMO. I guess my frustration is around the ignorance of sellers (I shouldn't be surprised, I know) and the lack of definitive info on the internet. There are a ton of part numbers tossed around, but no definitive info. I'm an engineer and that makes my red a** flare up. I was disappointed when I called Yesterdays Tractors and the sales rep couldn't tell me which harness I needed, whether it came with instructions, if there was a wiring diagram, if it supported lights, etc.
Thanks for the information. I'm going to see if the extant harness is reparable, otherwise I'll just buy a C9NN14A103B 2-piece and make it work.

Yep, and I'm 55. Do you want your doctor to lose the parts manual just because you're 47?

I never drive my tractors at night so I take the lights off of them.
Less aggravation

YT isn't the doctor. CNH is as close as you are going to get. Your medical doctor is just 'practicing' too. Best that you sit down, study & learn your tractor & not be so dependent.

| | Posted: Sat Jun 04, 2016 3:56 am Post subject: Re: 1969 Ford 4000 Diesel Wiring Harness | D3NN14A103 was the original part number for a European made 4000 tractor. The description on the parts site just says 'Main Harness', it does not say 'Front'.
The original part number is no longer available and has been superseded by part number 81830069, but the description hasn't change, it still just says 'Main Harness'.
If you Google either of those part numbers almost all hits returned will say 'Front Wiring Harness'. Given that the only thing rearward of the dashboard that is electrical was the rear lights and trailer wiring, and in the parts drawing for the 'Rear Lamps & Wiring' there is another wiring harness listed that is described as 'Wire Harness Assembly, From Main Harness', which has a couple of part numbers depending on whether it has brake lights or not, I would say that calling the Main Wiring Harness the 'Front Wiring Harness' is a fair description.

Asking questions is how I learn. If I didn't think there was a wealth of knowledge on this forum, I wouldn't have joined. Sorry if this upsets you. Like I said, I've had this tractor for a few weeks. Many of you have been around them for years and probably take for granted as 'basic' a lot of things that many 'newbies' are still trying to figure out.

Asking, reading, doing is how we all learn. No upset on my part. Maybe on yours, with 'my red a** flare up'. I was just saying that which you said later, 'asking, trying to learn.' is how you get there. We are all willing to help.

| | Posted: Sat Jun 04, 2016 12:22 pm Post subject: Re: 1969 Ford 4000 Diesel Wiring Harness | Those European models had funny multi position light switches that are expensive even in aftermarket brands . unless you need high / low / turn signal / brake lights just get a on / off switch .
You have one hot wire that comes from the key switch . it needs a ten amp fuse before the switch then one wire to the head lights .
It is an axillary circuit so there is no reason to mess with the whole harness unless you just want to . The new led lights look odd but actually outperform the old glass incandescent lights many times over . your call .
You will be way ahead to buy the FO31 repair manual and read every page . do you know how to check the hydraulic fluid level , the trans gear oil , which injector pump you have , how to check / add oil to the injector pump ? The fo31 will help keep your 4000 running properly

I appreciate the help. I'm not upset with anyone here.
I'm wondering why someone would cut the harness to all of the lights. Short to ground somewhere that they couldn't be bothered to find / fix? That upsets me, but I'll fix it and move on.
