Ignition switch failure/ headlight relay kit

I thought I would just use the lighting harness that was on the bike and just attach relays to it under the tank extremely simple when you get to looking at it have less than $20 after tubing and all the connectors and relays not that bad.
 


A Bloody good idea if you haven't done the headlight relay mod trick,
On that note any adition you make to your bike eg Heated Grips, Air horn etc you should run through a Relay

yeah that all it cost me you cut the wires just under the right side of the tank where they come out of the main harness the wireing to the light from that point is fine to use, you only need to add enough wire to allow you to put the relay back under the tank, when you cut the wire there is an extra wire going to the park light don't cut it and you cut both (dual headlights on std, clasics) sets of wires come from under the tank but you insulate and not use one set as you only need one set to switch relay you just take one (low beam) to one relay and the other (high beam) to the other relay.
I used 30amp heavy duty (insulated) daul core wire (spliced extra wire for second relay at relay end you are only useing one relay at a time) from battery for both positive and negative you could get your negative by just earthing to the frame but from past experiences I have found it better to get it directly from battery

Just Remember to make All connection good and solid by Soldering and throughally Insullating remember Heat Shrink tubbing is your friend
 
... remember Heat Shrink tubbing is your friend
It is until that one time you forget to put it on the wire prior to soldering the connection. LOL
I do that at least once on each project.
 
How does your bike handle in turns towing that trailer loaded to capacity?
Quite well but like driveing a car with a trailer or Caravan you need to adjust your speed and style eg slow down a bit

What is the primary use for this relay?

The relay or relays are to take the load of the ignition switch which can't handle the load and will eventually self destruct as many have found out, I heard about just after getting my Rocket, sussed it out and sorted it, no more worries, other makers stopped doing this stupid thing of run all the power through the ignition switch years ago
