Ok, i'll figure it out in a few days cos i'll have to leave now a bit, just confirm that everything except the engine and it's loom are in situ on the D2 body and not cut i mean fuseboxes and other looms cos that's important for this to work, also is the td5 ECU's black plug still there in the engie bay, cos that's not part of the engine harness which contains only thre red plug?
 
I'm on it just tell me few things cos i need to know how to proceed, are you up to run your own wires for speedo and tachometer(i'll tell you the wires where to connnect at the instrument packs's plug) or should i find circuits from the D2's instrument pack plugs or under the dash to the td5 ECU's black plug and splice into those?
 
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

thanks my friend
I have put tempory d2 body on to d1 chassis and engine today have put some tempary wires in for battery and earths ect
I put dash in as well I will get instrument cluster tomorrow and start doing some wiring to see what I get working
thanks again
speak soon
mike
 
No hurry, concentrate and think twice before you cut :cool:.... it's not easy but doable and at the end it should be OK without being an ugly bodge :rolleyes:, as long as the diagrams are accurate there's no reason to not work
