Relay information needed urgently, please.

[mikeyboy]

Hi, I am hoping someone can help me out.... I have just got a 1990 520i automatic as a non runner. The car was going to be scrapped due to a leaky transmission so the owner let people take parts off of the car. So to my point, all of the relays from both left and right engine bay compartments have been removed. I have got a number of relays from good old ebay but i need to know where to put them, as the engine does not even run. I could try guessing but I don't want to fry the electrics. So any help in the way of drawings or photos would be really appreciated, to help getting my first beemer running. Thanks.

hmmmm i would suggest posting your location,then hopefully someone with a 520 will hook up with you.The 520 is a model that was not available in the US so bentley manual may be of limited use,in the meantime trye34.net there are pictures there of the ,boxes in question

[mikeyboy]

I am in Britain, but maybe the 525 is similar if not the same as far as electrics go?? I have checked other postings but there dont seem to be any fuse/relay boxes that look like my one,

[Paul in NZ]

yes thats a possibility too i think the 520 was a different spec in many cases.Have you tried a web search on 520 E34,s?

[mikeyboy]

Yeah, I have spent ages trawling the net, what I seem to have learnt is that there always seem to be what looks like an orange and a white relay in the compartment where the ecu lives, I tried to upload a picture but I don't see it! I think they are the fuel pump and main relays, maybe someone can confirm this?

It also depends on the year/month of production, options ordered with the new car, country specific items.
So it can be that there are many connections which even do not need a relay.
You can see the prongs of the plugs and the numbers, by that you can find something out what fits there.

and go to the online parts catalog, there are the relais shown and also the numbers of each prong. Many of the relais are mulit-purpose use

Thanks for all your help, I got her going tonight, (orange and white relays- fuel pump and dme) and she started second go, not bad after a year outside in Britain!! I tried some other relays and have got the horns and flashers working, only the lights, demister, blower motor and mirrors to do!!! Anyone know what colour relays do these?? It is a fairly basic mode, SE so theres not too much to go wrong. It doesnt have an LKM like most models, don't know why.

Shogun is not a Grand Master for nothing! Great job Shogun and congrats Mikeyboy for getting the car running.

Mikeyboy:
what year and month is the car built? Or better tell us the VIN and use some info in your profile also, that helps a lot to help you. (you mentioned 1992, but that can be from 01-12 and in between is the facelift always every year).
Then someone with an E34 Bentley Repair Manual can have a look into it depending on the model year.
But the Bentley is mainly for the US cars, so there might be some small difference.

That you do not have an LKM is probably due to the fact that you have the low version, that means without check control.
Maybe in this case easier to solve all the outstanding questions.

Maybe someone can make a pic from his fuse box and mark the relais also for you.
Look into the sockets for the relais. The relay prongs also have a description. So you just read what is written and find the matching socket.
