Sorry for the thread resurrection but isn't the guide on the Samba just putting extra load/feed through the switch if you are splicing into the fuse to switch side rather than the switch to light side?
Not great with electricity but it looks rather straight forward. Edited by BobbyH - 05 Dec 17 at 07:28 |

I have all the parts, and understand the basics, it just looks as though the Samba guide feeds in to the fuse to switch/stalk side rather than the feed direct to the lights so I was wondering doesn't that just push all the load through the switch? Which is what I thought a relay was meant to avoid.
If so where is it best to interrupt to add the relay? |

P.S. don't forget the wiring load, if you are not sure get the kit linked above or similar.
I remember the formula as Virgins Are Rare. Volts over Amps * Resistance or (Watts) So a 60W bulb would give 12/60*Watts a 5amp load. A 100W bulb 12/100*Watts a 8.33amp load. Always leave a safety margin, for the above example I'd use 16amp cable and a 10amp fuse. Edited by AndyT - 08 Dec 17 at 17:36 |
