Temperature gauge/ Electrical issues

Hi all!

New to this site. I own a Lhassa green Mk1 Gti but am currently restoring a Mk2 2.0L Driver for the mrs. Its got a few electrical gremlins I'm hoping someone may be able to help with?
Firstly the  CE2 version (1992). The temperature gauge only works when I turn the headlights on??!!. Also I can not get the horn to work. Ive changed the X relay, the temp senders etc. Also the rad fan is very intermittent, it will come on then go straight off after 3 secs or so.
Anyone experienced similar issues? Any help is greatly appreciated, thanks, Dom

Don't know about most of your problems but does the horn contact on the back of the steering wheel making contact via the wheel slip ring? I presume you have checked the horn does operate if you attach a live feed.

Yes I have tried this. The horn does work with a live feed to it

Your only option is to use the wiring diagram from the Haynes manual and check all the connections for faults using a multi meter.  I would be checking for obvious signs of corrosion, for example at the main connection for the fan, as they tend to get corroded with age, and broken wires.
