400i Wiring Diagrams

Paul

1979, but I'm totally biased. My car is a 1980 400i.

I think that the 412 wiring must be very similar to the series II 400i, except for the addition of power seats on the electrics side. So it really might be more useful to do the series I 400i as series II owners could use the 412 diagram (I presume it is available separately from the manual).

I'm in whichever you decide to do, thanks!

The 412 also has ABS so I'm not sure how much additional wiring that entails but it could end up being quite a bit different than the series 2 400i.

AFAIK, the main electrical differences between series 1 and series 2 are in the use of solenoids to actuate the hood, trunk and gas cap cover releases.

Either series 1 or series 2 would work although my thinking is that using the diagram with more wiring is better than the one with less.

The fact that I own a series 2 400i has absolutely nothing to do with this opinion!

You are selling yours, so your opinion does not count.

I have done a lot of electrical work on 400/412. There are many small differences over the years. Also dual and single air. I always found the diagram in the brown 1985 400i owners manual to be a pretty good compromise and always figured out what I needed to. I used that one extensively.

I think the 412 is enough different that a seperate diagram is called for. The ignition is totally different and as was already mentioned there is the optional ABS, the electric seats etc. It really is a very different car electrically.

 

I just mailed Paul 308 a very enlarged set(2x3) of Series I wiring diagrams and wire color charts so that he can easily read them. I've been encouraging him to make us some diagrams, so keep encouraging him so that he can anticipate the amount of interest in making them for us.. I have been very much aided by his wonderful 308 diagrams as many of the systems are similar, but 400i specific diagrams that are printable/disposable when they are bent, torn and greasy would be a HUGE benefit.Yup.

Hmmmmmmmmmmm, stay tuned!

 

400i cars
_________

1979 to 1982 = Series 1---use the '79 manual
1983 to 1985 = Serries 2--use the '82 manual

FYI, I have the 291/83 wiring diagram manual & I find differences between it, the OM (250/82), & what I've discovered in my '83 Series 2 car...fwiw.

 

I looked into this and all links to purchase the wiring diagrams anywhere do not work anymore. As Paul was already 82 3 years ago and his last posts are also 3 years old I hope he just retired. Can anyone please help with a colorized wiring diagram for a 400 gen2?
That would be great. Or if Paul can be still be reached contact data would be great.
Thanks a lot
Christopher

 

Hi Christopher,

I've been searching for those too, but I believe that Paul has passed away :-(

Hi Esben,

it sadly seems to be the case. If I find something I will post it and let you know.

Cheers
Christopher

 

Thanks!

 

The Way Back Machine has a few cache's of the old website, but it likely was unable to archive the actual download pdfs. Probably what you really need to do is see if anyone who actually purchased these can share them here.

Unfortunately the diagram is for the original 400i, not gen2. I will dig into my archives to see what I've downloaded from his collection and will let you know.

 

That would be very helpful, thanks

 

Actually - that would be wonderful if you could share the Series 1 diagram, as that is pertinent to me. Thank you.

 

As this is not free content to be published online, I've made a small private conversation on the subject. If anyone else is interested to be in the loop, just PM me.

 

Raemin, that is great of you. Thanks a lot!

 

Raemin, would it be possible to be included in the email with the diagram? My car is 400GT, 1977. Thx a lot
