[QUOTE="SPECIAL LOCATION, post: 535185, member: 250"] Cable colours in this situation mean very little at all.. There are multiple ways to wire up two-way switching.. you will need a permanent live feed coming in. switched live strapper wires between the switches and a switched live out to the load (light). The live in & out may be at the same switch with three strappers. or live in & out at different switches with two strappers. Would guess your live in & out are the Red & Black of a T&E cable Your strappers were Red / Yellow / Blue of a 3core&E cable but for some reason blue needed as a strapper has been disconnected in the past..??? Easiest and safest way is to use a continuity tester/meter with the power turned off to identify which wires are which between the switches. Otherwise it's a bit of guess work as to which colours were originally used. [/QUOTE]
