Immobiliser Issue with Dials

[sie77]

This afternoon i eventually got round to replacing my black dials with white ones and everything seemed to go fine. i read on here it is best to change the facia rather than the complete clocks but when i reconnected my clocks i'm now getting the immobiliser flashing and when i start the car it cuts out within a second, any ideas?

*** Ignore this got it fixed i didn't put the plastic cover on, feel kinda stupid lol ***

Plastic cover shouldn't have fixed your problem, but it seems to have lol

I thought it was a good idea to leave the cover off so i could adjust the needles but as soon as i put the cover back on the immobiliser light went off. I'm not going to touch it now even though my petrol gauge is a few mm out
