Hi Ginge. It makes a nice change to see someone on here asking a question rather than commenting on the death of the site!
Ignition barrel does seem to be good place to check for a start. If the barrel checks as good I'd look at the big connector between the engine bay & the bulkhead. I assume you had it apart to remove the dash & replace the heater matrix? I'm just fishing but wonder if it hadn't gone back together securely. Check for corrosion, any signs of a pin overheating, and potential poor pin tension on the female side of the connector. The other immediate thought is a poorly secured ground on the dash-side of the bulkhead.
Like I say, that's just blindly fishing for ideas & I'd really want to study a wiring diagram to try to see a link between all of the things that aren't working. The headlights are a bit of an outlier as they aren't ignition dependent. That might be unrelated. I do have access to Sedre but the wiring diagrams in that are pretty rubbish & very hard to read, mostly because of the coding system Peugeot used. If you haven't got any diagrams you could do an Autodata trial (https://www.autodata-group.com/uk/buy-autodata/). I did it for my XSi a few years ago & downloaded all of the wiring diagrams I could before cancelling. You have to be really careful to cancel it before the month is up or you get rolled on to a VERY expensive subscription.
