Hi guys. Finally got around to replacing the ignition assembly and steering lock on the disco with manual tranny. The kit came from Brit part with new keys and looked great! Once installed- the illuminated color ring is on all the time. I have no comparison, as the old one never worked.
Advice? All the connectors are checked and truck starts and runs fine. I don’t want the batttey to drain. Many thanks!

Fwiw, Mine is green and does not stay illuminated. I believe it comes on when the door is open.

i should add, that with the center headliner light switch in the upper off position the ignition light “ red ring” does turn off. When the headliner light switch is in the “ middle position” is what keeps the red ignition ring illuminated all of the time.
Maybe the new ignition is fine and I have a bad door switch somewhere?? I will keep looking. Other forums have noted this condition:
” truck has always done that”
”I took the bulb out”
etc etc
I do not want a constant draw on the battery- so for now will just keep the interior dome lights turned off completely.

Correction, mine is amber/orange. Wife’s is green.

Just wanted to update this thread. Action steps so far:
1. Removed the MFU from behind drivers fuse panel. Checked for corrosion and that all plugs were secure.
2. Removed the airbag knee bar to make sure that nothing in the ignition harness was getting pinched or wear spots with any zip ties.
3. Cleaned and replaced the 3 associated fuses with MFU
4. Replaced the (5) door switches
5. Checked all grounds at battery, chassis and starter
7. Removed the britpart ignition assembly in favor of the Lucas version which is hopefully better quality.

Will post up more when everything is buttoned up. Fingers crossed that this is solved!

So replacing the britpart ignition switch with a Lucas kit solved the initial problem. However, I wanted the dome light timer to work properly also. I removed the MFU and cleaned and inspected it- mixed result. After a few attempts at it- I opted for a new MFU from dealer. They are about to discontinue these- so if you are keeping your Disco long term, you might consider getting a brand new one and being 100% done with all the light issues. Very happy to have this resolved! The 1st trip into the fuse panel was a few hours, the last trip in to replace MFU was 20 min. The learning curve applies!

What was the cost for a new one? And part number if you remember.

AMR1280, special order at dealer. They quoted list at $465!! Selling prices all over the map. Fleabay has some listed at $45. In my case, the Trek deserves new parts when still available. Whatever you choose- the important thing is these electrical issues are all fixable.
