Lancia Montecarlo - Wiring

now that would be a nightmare for me but when it comes to 'wires' your the expert

Haha yes, you could almost call me a wizard. But as the title says, I do it for fun rather than reward!

Hi Rachael,

That is a lot of extra wiring, any idea why it was added ? I remember the Lancia Montecarlo a friend of mine had one, very nice cars.

Best wishes,

Geoffrey.

Hi Geoffrey,

The car has had a few modifications, it had the original rectangular(ish) headlights converted to twin 5.75" round headlights from a BMW 3 series, also there were driving and fog lights added along with associated toggle switches. There was also a wiper relay mod to improve the wiper speed.

In the cabin, the original ceramic type fuse boxes were replaced by aftermarket blade type fuse boxes, which were nice but there was no means of identifying what fuse served what. A CD radio and some extra gauges were added with wires going everywhere and using Scotchloks and "chocolate strip". There have been other wiring repairs made with not very durable methods!

Scotchloks - oh dear, especially when used to wire in an alarm system ! Hope it all goes well and that there are no intermittants.

Best wishes,

Geoffrey.

Here I have wired the ignition, lighting and dip/main beam switches. It's hard to tell but this is done in thinwall cable in much smaller sizes than original since the switches are no longer carrying heavy current...


As the dipped and main beams are operated via relays, I have "reversed" the circuits such that the column switch is on the earth side of the relay coils. What was the supply wire to the switch is then run to earth. This is inherently safer and less likely to release smoke than original set up because if any wire to/from the column switch is shorted to earth it simply operates the affected relay; if a wire is shorted to 12 V, nothing happens.
