Ok so recently I’ve signed up to this American guy scannerdanner, great info and tips etc and very well put together.

However he often uses wiring diagrams and sources them from sites like Mitchell and another run by Snapon

He can access wiring diagrams for almost any circuit in which ever car he’s working at.

I myself have been using auto data but find the wiring diagrams terrible I.e it’s mostly engine ecu and maybe abs ecu and that’s it.

For example I had a transit with no dash instrument cluster lights working and I found it impossible to find a wiring diagram to check for a feed I ended up sending the job out to another garage because I couldn’t be sure it was the cluster and didn’t want to just start wasting money if I didn’t need it.

So I’m just curious as to where others get their wiring diagrams from based on the uk

From another software - Haynes pro, Autodata..

I get diagrams from würth Wow and autodata 8-)
