015 Meriva B Maintenance questions

[muir546]

Firstly, I'm after a decent electrical circuit diagram. I don't want to buy a Haynes Manual as they are an  expensive purchase of poor quality photos and I'm not sure on the circuit diagram photos, so any advice for good workshop info. Although my trade was close to that of a car mechanic, that was 20 year ago and a lot has changed, I just want to do my own work. 

Secondly, I have 17 inch alloys but no spare, I'm trying to get my hands on spare alloy or full size steel wheel but I'm getting no joy as to brand new prices.

Thirdly,

The wheel change and breakdown kit is also missing so any advice on getting replacements would be much appreciated 

Many thanks for any help
