going to get some heated grips at weekend to fit to my GTS250ie. noticed in a previous article about a tom tom, that it was wired into the cigarette lighter.
where is this cigarette lighter? i cant find one. i have open up the left knee pad and can only find wiring for the indicators.
can i wire off that funny little light in the horn casing?
tahnsk in anticipation of your help

The lighter socket is optional m8. I just wired my tomtom straight in to the switched live behind the kneepad.

You need a decent power supply for heated grips... best go direct to the battery or fusebox really....

As Tom says, heated grips use a lot of electrical current. Take his advice, or you'll end up with melted wiring.

Anything that involves heat means high power consumption so do pick carefully when wiring them in... youll find most say wire direct to the battery... if not run them direct from the battery with a relay to switch on with the ignition.

sound complicated. they are going to draw 8 amps. going straight off the battery is the right way except you can easily leave them on.
so i think i shall find a wire off the fuse box or plug it straight into the fuse
anyone know the best fuse. by the way the grips come with an inline fuse too.

i have had them on a previous scooter. they were wired off the side light. nothing melted, but i guess one day it might have

I dont think there will be any available wire which i would trust to not only take its original desired load, plus another 8amp....

Wire them direct, and if you must have ignition live feed only, then wire them through a relay, so the grips are powered direct from the battery but only when the ignition is on...

whats a relay?
and what about wiring straight into the fuse box

The reason you cant just wire off the fusebox, is the fact that all the wires in there are already used, you cant just try to pull another 8 amp through a wire already carrying it... if there was an unused feed you could, but unfortunately there isnt on the GTS.

Think of a relay as a electronic switch...

A relay is a small plastic cube shaped thing with ( usually ) four terminals on it. The terminals are usually numbered 30, 87, 85 and 86. Get one that's suitable for the amount of current that you want to put through it, and wire it as follows : Pin 30 - permanent live ( can be taken direct from the battery positive terminal via a suitable fuse ). Pin 87 - this goes to the positive side of the component that you want to power up. Pin 85 - put this to a good earthing point. Pin 86 - wire this in to an ignition live feed in your wiring loom. Don't forget to earth the negative side of the component that you are wiring up. When you switch on your ignition, you put electricity through the relay via pin 86, this then goes through a coil of wire wrapped around an iron core, and earths via pin 85. This action causes an electro-magnet to pull down and bridge pins 30 and 87, thus powering up your component. You therefore only need heavy wiring on pins 30 and 87, and thin wiring on pins 85 and 86. you can also put an on/off switch in the wiring to pins 85 or 86, so that your component is not on all the time that the ignition is switched on. Hope that's all clear ! - here endeth the lesson.

Once again I'm indebted to the advice and knowledge shared by others in this Forum. Thanks jetex.
