Headlamp dimmer controlled foglamps

[DJ BFG]

Your talking about your Yamaha R1 right? nice I have a Yamaha R6, so tell me about your mod on the Bike...

Okay, so here is MMD's Easier than cutting pie lighting installation instructions!

First, let's go through some basic wire splicing techniques. There are several different types of splices on the market and I will give you and example of a couple. One (the blue one) is a simple butt splice, okay for interior use and areas where moisture, corrosion, etc., are not a factor. The second ( black one) is a bare type splice with a heat shrink cover that has an adhesive lining that oozes out the ends (hopefully you can see that in the pic) sealing the connection. Use anywhere exterior or where dirt, debris, moisture, etc., can access splice.



Trim each end of the wire approximately 1/4"



Make your connections and wahlah!







Okay, now for the install:

Let's make that "wonerful connection behind the glove compartment! Select the wire color for the switch you intend to use and mate it with a chosen color to one of the pass thru wires that ends up in the engine compartment.

Sorry, the second to last photo is sideways.

Now, at this point, if you are going to just run your lamps from the Aux switch you would use the corresponding pass-thru wire that you connected earlier to the power wire of the lamps. (in this case the white one)



And then the black wire to a suitable ground.



In this case I have modified the supplied harness from PIAA so the combination of the two white wires at each lamp are now going to be twisted together and then connected to the pass-thru wire using the splicing instructions from above. The black ground wire is already combined and will be connected to the ground on the fenderwell.



After mounting your lamps in your desired location, connect the manufacturer supplied connectors and you are finished!



Easy as pie baby!!

Now, for the dimmer controlled install:

After making your initial connection (behind the glove compartment) and now having a switch controlled wire to the engine compartment, we will begin by accessing the high beam circuit for our relay trigger wire.
CAREFULLY, remove your right (passenger side) headlamp.



We will locate the yellow wire at the headlamp connector and make a Y-splice using the splicing techniques above. Use enough wire to reach the area where the pass thru ends are. After making your splice, route the wire up through the fender behind the headlight and near the inner fender. Leave yourself plenty of wire to work with.




Re-install your headlamp. Now there are two of the necessary 4 wires at the point of installing the relay. Here is a diagram that should help you understand what to connect.



I am going to use a pigtail connector kit that will make the relay installation cleaner than just female spade connectors. The part number for the pigtail kit is WPT-802.


Find a suitable location for the relay, make sure your wiring is long enough to reach the relay, and make the connections as shown in the do-it-yourselfer "map" above. Your fog lamps will now work as we described earlier in the thread.

NOTE: You will notice that in the "map", the 87a terminal is not connected to anything. This is done to open our circuit to the fog lamps when the relay is triggered by the high beam circuit. You may want to cover that terminal with a plastic coated female spade if you are using spade connectors as opposed to the pigtail kit so it is not exposed.

There you have it! Hope it is useful.

Sweet install buddy! How long did it take us to get this hashed out <G>. This is the thread where we met... on the "Other" forums. Good to see it over here where it belongs and finished!

Awesome job FS! Totally KB worthy. I'll add it when I get in front of a computer tomorrow.

I recall.................FET and MOS. <GG> For your desired install, use the park lamp circuit at the same headlamp and wire it to a 4-pin relay to be energized when the headlamps are on and de-energized when they are off, no matter the position of the Aux switch.

You're reading my mind... cool! (disregard that bit about the midgets and the goat... <G>)

Great write-up. I think I may be able to do this mod now...I know I can. Thanks FSM.
