If you look at the wires going into the top of the relays the horn relay has a purple feed into one of the terminals which then loops to another pin. This looped purple needs to be removed from the relay and the connection replaced with an earth feed. There is a convenient earth on a nearby relay you could splice into or as per GD, use the spare black earth feed on the redundant door interior light wires that run very close to the relay block. Simon R has a wiring diagram he produced for the mod on his blog site.<br /><br />RyanRyanhttps://www.blogger.com/profile/11160221437729717188noreply@blogger.comtag:blogger.com,1999:blog-785166878810501762.post-36284207022424198662010-11-15T13:52:42.517+00:002010-11-15T13:52:42.517+00:00Ryan what mod is needed on the relay part of the w...Ryan what mod is needed on the relay part of the wiring loom, I havnt fitted my loom yet so would be handy to do the mod first. :)Cobra Robhttps://www.blogger.com/profile/04861614901532506299noreply@blogger.com
