UK Car Repair: astra gsi dash, vauxhall astra gsi, fuse holders

Question
I own an mk3 vauxhall astra gsi 2.0l 16v j reg 1991.I recently removed an immobiliser that was faulty,after i put everything back i noticed there are no ignition/warning lights coming on.everything else works fine & the car starts no bother.I have checked fuses & bulbs they are all fine.I would be grateful if you could give me a step by step guide to repair it but any help will be fantastic.Thank you.

Answer
need to know model of immobiliser to make easy guide.

Get some tape in any case.
For now.. Check for cut wires near ignition and fusebox n relay box. youll have to untape at least 8'' from the immob splices to find any cut and hidden wires. Check exhaustively 4 bad loose rusty connectors on fusebox relays fuse holders loom and dash.+

if no joy get me the model no.
