Discovery 3 to Discovery 4.5 facelift mirrors - help please

Hi all,

i am wishing someone on here can point me in the right direction, i have spoken to some people on the forum but i am still unable to fully work things out.

this is as far as i have got:
Left is D4.5 Mirror and right is D3 Mirror:
Credit to this goes to @Emmet McKnight so thank you!
1. Red/White to 1. Black/Pink
2. Light Green to 2. Green/White (Silver/White on diagram?)
3. Blue to 3. Black/Blue (Not yet as it will cause issues)
4. Pink to 7. Yellow/Red (Not yet as it will cause issues)
5. Black/Grey to 4. Brown/Purple
6. Black/Blue to 5. Black
7. Yellow/Red to 1. Red
8. White to 2. Green
9. Brown to 4. Yellow
10. Grey to 3. Black
11. Dark Green to 8. (Approach/puddle lamp)
12. Indicator positive (Not mentioned but assume you have it).

I did connect this up but quickly realised that what Emmet mentioned is that a soldered joint needs to be unsoldered in the mirror and a new wire soldered, i am assuming this is because the one wire has two functions, moving the mirror up and folding in, which explains why when i had it previously connected for a year or so, everytime i folded out, the mirror would face the sky! Surprised im unclear as to where i need to unsolder, can anyone provide some insight? currently my mirror is off the car and i have dismantled it and it looks like the below.



any direction would really help as i hope to get this sorted otherwise i will just have to plug them in without folding and mirror motor adjustments Big Cry Big Cry Big Cry

thank you so much in advance, any help is highly appreciated

Sent you a PM,

I have noticed while helping out people with this mod, that certain year cars have a slightly different colour coding to the wiring. The list above from Emmet is one that I sent him specific to his cars colours and may not be correct for every year.

If anyone plans this mod, leave the connectors fitted and PM me. The Land Rover diagrams don’t list wire colours in the mirror as it’s a non repairable item or LRI (line replaceable item). It’s easier to list which pin connects to which pin, and which wire needs splitting and extending than it is to use wire codes.

Just noticed your Q about the solder joint. On the D4.5 mirror, follow the wire in pin 3 back through the loom until you see a piece of blue or black insulation tape. Remove the tape and you will see a solder joint. Remove one wire and solder on a new piece. Re-wrap both joints in tape. Now you need to work out which wire does what and where you put them back into the plug. That is in the PM I’ve sent.

If I ever get some down time from work I’ll do a proper post but I’m that busy at work it’s always at the bottom of my list. I’ve even thought about doing a near plug and play harness for this or a mod service but I don’t have the time and it may be to expensive.

thought id give everyone here an update,

a MASSIVE thank you to M3bobby who helped me sort out this mirror, it is now working perfectly! thank you! i managed to unsolder the part, route a new wire through and connect it all according to M3bobby's wiring instructions! i had a hiccup (due to my own error) where i was connecting all 3 black pins to the same black/blue wire when one of the black wires from the memory loom on the door was actually meant to be connected to the grey wire in the mirror loom.

Thank you so much, after 2 years of trying and giving up, it is finally done. Thank you to M3bobby and Emmet McKnight.

Have a good night all!

forgot to add that the issue i had when i had all 3 earth wires connected to the same black/blue wire, it used to stop moving a certain direction after 1 second, so for example, i move it left, it moves for 1 second then stops, i have to let go, then press left again for it to move again for another 1 second and that would happen for all directions, the fix was to have the memory door loom black earth wire connected to the grey wire mirror loom
