I have just reached the stage of wiring up the steering column switches (Sierra) to the Velocity loom supplied by Luego. My problem is with the light switch I can find the connections for the side lights but not headlamps. The switch has all the correct connections for the wipers according to the Haines manual but three of the connections (W, 53c and 53a) seem to be connected together when everything is off. On switching to headlamp a connection is made between 56 and these three. Can anyone help???

Be aware there are a few different Sierra light switchs and they are wired differently. Use part number on switch as a guide BOL
