1994 Discovery 1 v8 wiring diagram.

[DAMINK]

Hi all, been a long time....
anyhoo i purchased the rave cd from the store here at aulro.com some time ago. I now find myself needing to access the wiring diagram for the old beast only to find the cd seems to not contain said diagram?
The cd i have is marked RAVE CD II. It does contain D2 info and defender info. However it does not have a D1 category.
Am i to assume the defender v8 is the same wiring as the D1?
If not have i acquired the wrong cd?

I need the wiring diagram of the whole car really as im about to remove the dash and strip out all the old wiring and rewire it all neatly.
An after market alarm installed by a non auto elec has turned my already messy wiring loom into a complete puzzle.
And a recent short has turned it into a priority fix.

Any help/advice appreciated thanks.

Andrew.

Most of the loom is probably still in good order. Find the smoked wire/s and remove them. Tape up any adjacent scorched wires. Alarms are usually easy to remove as all you need to do is strip back the installer's tape mess until you find matching coloured wires each side of the cut. Any wires just tapped into (such as indicators etc) just need the offending wire trimmed off and taped.

Before recreating an entire harness just find a reasonable one out of a wreck. Not sure why you need a wiring diagram, often all you need is the standard colour of the wire to identify it. Plenty of wire colour charts and wiring diagrams online, here's just one site:

Thanks for that link, that may well go a long way to helping me. Bookmarked.

Its a right mess man. The whole car truth be told. Many owners and each one seemed to have had a go at playing electrician, me included.

Here is a pic to show ya the mess i have before me hahaha. There is more "mess" behind the dash too from other hacking.

My short was the ignition wire, no doubt a result of the immobilizer wiring part of the alarm shorting somewhere.... yet to find exactly where. I was stuck in the bush and went the hack on the loom trying to locate the short. Took me 2 days to get the car running and home :)
Ripping out a fair amount of the alarm wiring which in turn killed the central locking, got it going and home but now feel i need to treat my car to a bit of love.
The alarm i plan to keep as it works well....... when its not cooking ignition wires :)
The problem is the alarm was installed poor to say the least. Some wires looped around others and over steering column etc. Just a mess and the alarm unit hangs in mid air.
I have a few loose relays and one fuse block floating also. Many wires not terminated at all.
My intention was to mount the alarm properly behind the dash, shock sensors etc etc and then wire them all in neatly. Soldering all connections and heat shrinking them and finally putting them all in a tidy loom cable tied together.
Rather than trying to reuse the old wiring i was planning to just change out a heap of it one wire at a time and making it tidy enough i would be willing to show it off.

I really want to do this one time and one time only. Properly and tidy. I know its going to cost a few bux in supplies and a bit of time.
This old car has taken me places i never expected it could and has got me home time after time after time. Even when i have trouble it still gets me home.
Thats why i really want to do it properly and once.
Damn long post sorry.

Yep its a mess.
Gives me a goal though, to fix this problem once and for all. Clean and tidy and hopefully never have to look at the loom again.

Getting back to the original question to some extend. The Rave disk i purchased.
I noticed there is no RAVE CD II in the store. Only a RAVE CD I ??

Was i given the wrong cd when i purchased? Was it old stock or something? Can i use the disk and go off the defender v8 diagram?

Discovery 1 Workshop manual (http://www.landroverresource.com/docs/D1_Workshop_Manual.pdf)

the link may open up as a PDF directly in your browser. If so just save it to your computer or whatever device you're using.
Only problem is with this one, is that it's for the update model(1995 onwards) .. so for sure some things will be different.
But having access to it could still be helpful.

I have a Haynes, and while they aren't as good nor detailed as the RAVE workshop info, they're better than nothing.
And it will have the pre update model specific wiring diagram too.

Thanks for the links guys.
Bee Uteys link is the best one so far or the closest to what i need rather.

Ultimately i want to be able to find what every wire is for and where it goes. Colors etc.
The above 2 links do not go into that detail at all. Rather just broad info.

My D1 is a 98 build, so there are going to be differences, but my key courtesy light does turn off.
I'm pretty sure that the globe is accessible in a separate small side housing hanging off the lock barrel. I can't remember if I changed mine to an LED(most globes have now been changed).

I did the small black wire mod to stop the annoying sound with the key in the ign and door open, but don't mind the lights on sound.
When I did that key in ign sound mod, I do remember seeing a small silver light sockety thing for this light.


...oops! wrong thread :p

Rave should have a full wiring diagram section and photos of component locations in the electrical section. Trouble is there are lots of doctored versions online

Of all the RAVE files I've found on the various sources online, and having purchased the CD from Dave, I've yet to see a proper full electrical diagram for the D1.
D2 no problems .. love the electrical circuits they cover, and used it many times to trace stuff and check stuff.
ATM, I'm reliant on the Haynes manual for any electrical work I ever need to do on my D1.

My D1 has central locking, but no remote system(no alarm, etc) and a while back I had an aftermarket kit to add a remote system with complete with new actuators and all wiring and stuff.
But I had all the wiring, all I needed was to add the remote box and connect the wiring.
Should have been easy, but not so.
I found the required wiring(basically one pink/orange wire and a pink grey wire .. or something to that effect).
No problemo, feed into the already in place wiring to save me a lot of install time.
Doing that tho added about a week of install time, as I could only get it to either lock, or unlock .. but not both! It was one but not the other.
Couldn't find any info on why both those main central locking wires had power to them at the same time.
In my mind, they appeared to be like a positive/negative pairing, like in all the kits have the wiring setup.
But both the main wires had power at the same time.
Nowhere did it describe how the central locking system worked.
I tried about 20 different combos of relays, relay types and wiring setups, and got close to the point of installing the entire kit I got, and bypassing the LR system.
But!
I eventually 'guessed' that if I remove the central locking fuse, it may help .. and bingo!
About 3 days of messing about trying to work out how to get it working, and all I needed was to remove a simple solitary fuse .. all because very little to zero info can be had on D1 electrical operation/circuits.

Solid, reliable and zero error operation remote central locking in a D1 [thumbsupbig] .. other than the totally hopeless plastic bodied remote fobs that comes in those tacky kits.

Don't get me wrong tho .. totally appreciate that some info on the D1 wiring is available in the RAVE CD that Dave has(that section is titled etlj970x.pdf for anyone having trouble finding the D1 electrics) .. it's just not the same as having a full wiring diagram like the D2 electrical section has, or the Haynes manual gives you.

Thanks anyway guys.......
Wiring frustrates the hell out of me.
If i cant obtain the adequate diagrams i need to concede i think.

Again thanks for helping guys i do appreciate it.

what year is your disco as the prefacelift D1 has a different manual.

lol sorry for the slow reply i thought ya must have been taking the ****.

1994 is the year which i clearly stated in the threat title. 1994 discovery 1 v8 wiring diagram.

Hi Im also trying to find wiring diagrams for my 94 V8 disco. fitting a 97 3.9lt engine in the 94 but i dont have the 94 engine harness and computer. trying to sort out the wiring difference is doing my head in.
