I've been pulling my hair out with problems with failure of steering column switches such as headlights/high beam, horn, wiper fluid motor, etc.

I've debated whether to replace entire switch sections, but then there's still a defect in the overall design which could lead to failure again in the future - i.e. high amps across the light switch instead of using a relay.

I've ended up wiring an alternative high beam switch (now using a relay with default feed to dip beam) and wiper fluid motor, but now switches are on the panel and not as convenient as having at your fingertips. The horn is driving me crazy as it is temperamental and of course never works when I really need it!

Does anyone have some creative solutions? Can you retrofit a better designed steering column switch package to a Landy? Any solutions to horn issues?

Make a search on here for relay circuits!!!
keeping the original switchgear and as you have done use relays to reduce the load on the original switches this works fine.
I have done it to my 2001 TD5 and used five relays (this is including the horn) this keeps each circuit separate for dip and main beam also added additional earth circuit.

It really very simple. I would just replace the switches and fit a relay.

Best way is like this.....

Find the live wire which activates the device (for this we can use the high beam)...

cut this wire and crimp a female spade connector onto each wire.

These will then become:

85 - Wire from steering column
87 - Wire to device



US1 - This is your steering column mounted switch

Then get a decent piece of black wire and fit a female spade to one end and a ring to the other. Attach the ring to a decent ground and the spade will become connector 86

All you need now is a live feed and fuse......

This will attach to the relay at number 30


My electrical tutorial explains a lot more about relays and other circuits (see my sig)

It's fairly common to have a single relay which takes the current off the main light switch, but the dip/main switch still takes full current. It's simple enough to rewire at the fusebox, so that there are separate relays for dip and main beam.
