disco 1 too disco 2 conversion

If I was doing a D2 body swap to D1 300tdi, id remove the 300tdi loom & chuck it in the D2 shell & just rewire the lights to
suit. Retro fit the cluster which wouldnt be too difficult. keeping the D2 loom & cluster ooofttt thats a head ache stuff that.
Id end up burning it. Before you do drop me a msg im always looking for unburnt projects.
That reminds me!
"Pass the matches love!" 🤣 🤣 🤣

Definitely maybe!I was thinking along those lines at one point but decided it might be easier, as suggested earlier in this thread, to leave the disco 2 wires in situ. Im getting on with the project, the wiring isn't too difficult just time consuming .just need two haynes manuals with both wiring diagrams.

You must be well skilled with electrics if a D2 is involved or better let it go
If you have the time......Ive wired as per your info (and a few more) but, normally when you turn the ignition key, the cluster lights come on for a few seconds then off. Do you know the feed wire colour for this to the cluster?And its counterpart on the disco 1 cluster? I assume there is a relay on a timer.?

Unfortunately I dont even understand what you mean by "cluster lights" or what's the problem cos if it's about warning lights it's normal behaviour to come on then off(on a D2), there is no timer, each system's ECU would extinguish the warning after a succesfull self check... based on your question about relay or timer this issue seems way above yor skills so i can't help much

thanks, We learn by asking questions .And ive learned a couple of things from your reply, one is its not a relay. The individual warning lights do come on if a circuit is created, but not initially when the key is turned, so not sure whats happening there.I am a dufus its true.
God bless. And as we say in Scotland "Up yer kilt"

i need to speak to anyone who has done this conversion bodywork is not a problem I will sort all thsat out I got td5body sitting on 300 chassis all seems ok couple of mounts to sort brackets for rear bumper no probs

I could realy do with speaking to someone that's done it already cause they will have the knowledge
I want to know if I can use the brake abs thingy on the pass side or do I have to take that out and use the equilizer valve on the 300
also how they went about putting a throttle pedel in and doing away with the potentiometer
regards
mike

oh and when done I will have a complete td5 engine auto box all on a running chassis for sale only 90000 miles realy sweet
I swapped the disco 1 brake pedal and servo, master and the equaliser.(And the brake lines) Its good to do this when you take the pedal box out for the throttle cable.(and not after you have everything in place and find out your disco 1 master cylinder will not fit the disco 2 servo.)

I don't know if its a prerequisite for the inspection (MOT, NCT) to have the cluster lights come on when the ignition key is turned?if i have to become inventive there are some crazy hacks out there. Stephen Fry will have a fit.

I want to help but i'm still confused so untill you dont explain clearely what's going on i can't help and that's the result of "hyjacking" an old thread with a first cryptic reply instead of describing with details what you worked untill now and what's not working as it should

So, did you transplant a 300 tdi engine into the D2 and now the warning lights are not coming on for self test or what's the problem cos i dont get it?

I thought it best to "hyjack" this thread in order to get all the information in one place. If anyone else is brave or stupid enough to take on a similar project It may be a help as similar problems are sure to crop up. I have been wondering just what i did to upset you.

I have also gone down the route of placing a disco 2 body on a disco 1 chassis with a 300 tdi engine, and took your advice and decided that wiring the disco 1 instrument cluster into the disco 2 harness was the best and easiest way to progress.

Talking with a knowledgeable mechanic today he is certain that warning lights should be seen to go on and off when the key is turned for Inspection/MOT .I have no warning lights coming on except the handbrake/brake fluid warning light,(there is no fluid in) and fuel gauge low warning light(there is no fuel in) He suggested wiring a timed relay! I wondered whether connecting all the warning lights to the glow plug "warning" light might be an idea?
I would suspect that trying to keep the ecu from running check lights protocol is probably wise as the lights would be permanently on for faults.

Ok, so if everything except the engine/ECU is untouched on the D2 body you should have all the body controll working on it(central door locking, alarm, exterior and interior lights, etc) for the starter you should find the BR wire with lucar connector in the engine bay and as long as the fob works the starter will work as well, to override the immobiliser you'll have to give direct earth to the starter relay's coil at fusebox plug C0573-7-BO, so here's the plan, remember vehicle-connector number-pin number- wire colour , and when i say "black plug" means D2-C0658(engine bay):(strangely some colours are mathcing between D1 and D2 :))

-cluster earth, all the B wires you find coming out of it connect them to B wires from D2 plugs or direct to body
-cluster feed:
D1-C222-2-LG to D2-C0230-19-LG
-cluster illumination: D1-C222-7/9-RN to D2-C0230-12-RN
-speedo: D1-C221-2-BR to D2-C0233-13-RS and the speed transducer signal into black plug pin 6-RS
-tachometer: D1-C207-5-WS run wire to the alternator
-fuel gauge: D1-C221-3-GB to D2-C0230-14-GB , you'll find GB wire at the D2 tank's plug
-coolant temp gauge: D1-C222-8-GU to D2-C0233-15-GU the temp sender signal to black plug pin 7-GU
-oil pressure: D1-C222-5-WN to D2-C0230-6-WN, you shopuld find a WN wire hanging in the engine bay
-direction indicators: D1-C207-4-G to D2 fusebox C0587-12-GR
-hazard: to D2's hazard switch LGR wire connect a relay's coil, other side of coil to live 12V and a 12V through relay's contact to D1-C207-9-LGG
-main beam: D1-C207-3-UW to D2 fusebox C0586-14-US
-handbrake/brake fluid level: D1- C222-3-KO to D2-C0230-10-KO, you should find KO in the engine bay where the brake fluid reservoir was


for the SRS and seatbelt warnings i'll have to think hard cos it's vague in the diagram and these were managed by the D1's MFU which is missing now, be aware that all these connections are based on both vehicle's diagrams and if something is not matching it might be a mistake in the diagram or my mistake so after you conncted wires dont install the cluster untill it's not tested or eventually i missed something... then if something is not OK we'll fix it "in situ" ... Good luck
Ive wired in a Disco1 Instrument cluster into the Disco 2 wiring loom using the instructions above I've
also added
- alternator warning D1-C221 5 N/Y- D2-C230-11-N/Y
For the speedo, I intend to run wire up to the instrument cluster from the vehicle speed sensor at the gearbox output, and take a live feed into it from the reverse light feed (which is live and in close proximity to speedo wire.
For the direction indicators I did
-direction indicators: D1-C207-4-G to D2 fusebox C0587-12-GR
Splicing into the wire from the fusebox meant that when operating the left hand indicators the "direction arrow " warning light flashes on the cluster.And also the hazard warning switch makes the "arrow warning light flash too. But nothing for the right hand side...so i again lay with my head in the footwell upside down with a torch and a screw driver , prised the connector out and spliced in another wire up to the dash.
-direction indicators: D1 -C207-9-G/LG to D2 fusebox C587-13-G/W
This connects a feed from the righthand indicator circuit up to the hazard warning light (red flashing triangle) on the instrument cluster. This means that when the right hand indicators are operated the red triangle icon flashes on the dash. And also now the hazard warning switch flashes both the direction arrow icon and the little red triangle icon .So there is no need to wire in a relay as suggested above.
In the original Disco 1 circuit both feeds go through a one way diode (remember them from school?) and light the same bulb (direction arrows icon) on the dash.
But Im happy this way and don't want anything more to do with the indicator/hazard warning circuits.

I have the engine out, so cant test the speedo or tachometer as yet but all of the rest of the above working, Phew.

Now it's clear ... as i said each warning light on the D2 is managed by each system's ECU and the BCU is also involved, the glow plug warning light is managed by the Td5 ECU based on engine coolant temperature input which i presume is missing... though if only the engine was changed the SRS and ABS related warnings should still work if the LEDs were not "disabled"... if the system was hurt somehow by the engine conversion the "3 amigos" should be permanently on ... connecting them all to a timed relay can trick the eye but you'll never know if the related systems are working or not so unless you want to use that vehicle only off road it can become dangerous in traffic on a slippery road without ABS or EBD activity.

anyway... if you want to emulate the warning light's ignition self test(which means they must come on then go out after few second if a fault is not present) i can tell you how

i have the engine out so cant test the speedo or tachometer
those are working only together with the TD5 engine ECU

Off topic* (AAMOF... IMO UK's reguations seem to be very permissive if you can get a MOT for such a "hybrid" :rolleyes:... they fail them here even if the VIN on the chassis doesnt match with the documents or the tyres are other than standard dimension... beside other illogical restrictions)

This thread would be so much better with pictures....
Im going to add some at some point. Ive kept the disco 1 bumper which is swallowed up with the longer 2 body leaving only a couple of inches protruding. looks strange but kinda neat. like a transit van bumper

Ive wired in the instrument cluster from the disco 1 remember ? Its a 1996 disco 1 three door van chassis. I dont have abs or ebd hardware in place . According to Mr Haynes wiring diagram I do have ABS warning lights and SRS Indicators 1 &2 so some disco 1's must have had the hardware. So that's a relief because srs warning light must go on and off, if you have airbags, for inspection purposes.

I believe Land rover were pioneers of traction control but it would be a few years later. (thats a dangerous thing to state on a land rover forum, an anorak is sure to come on now and put me right with some facts.)
This gets confusing alright. I should have just restored a disco 1.

YES please do explain how to emulate the warning lights ignition self test
