I bought a sidekick and I have fixed it all up and am going to put it on the road the only problem is the lights are messed. I have no lights and my brake lights are run off a switch. any idea how to fix this. Oh yeah and my 4x4 light is on and im not even in 4wd.

4x4 light is a wire coming from the transfer case.
I would start by tracing the wiring from the lights back to the switch.
Try to get a wiring diagram that shows the colors of the wires that you should be looking for.
the brake lights should go through a connection that is on the brake pedal.
Good luck.
if it's messed way to bad I would look at a wiring kit from painless wiring.

Check your fuses. If your brake lights are ran off a toggle switch...you have had a " master electrician " modifying stuff!   Get a simple circuit tester at the auto store. I asume the brake switch on the brake pedal is not functional. Get a new one and install it. Remove the " master electricians " handy work and check your brake lights.

Head lights...switch could be bad, check connections and test for power at the switch using the circuit tester. Electricity is a very simple creature. It flows out from the battery to a fuse block or in line fuse, then to your switches, which open and close the circuit on the hot wires (red) from your battery. From the switch, it flows to the accessary, lights, horn, wippers, what ever.  After power leaves the accessary, it travels back to the battery on the negative wire .All negative wires  usually ground to the frame or any other grounded metal surface that is close to the accessary.  " Master Electricians " sometimes run the ground wire all the way back to the battery. This works but is unnecessary. The battery is grounded to the frame by the negative battery cable. (black)

If something doesen't work there is a break somewhere in the  circut ( electrical loop ). Think of electricity as an unbroken circle with the battery, fuse box, accessary all inline with the circle. Find the break fix the problem.

If you would like I will send you a daigram of basic automotive wiring by email attch. Get back at me if I can clarify anything or speak to something specific. Step by step if necessary. I need to know your skill level to be specific though.

You can check switches with a jumper wire. Asuming the fuse is good,  Bypass the switch and if the accessary works the switch is bad. If you have power at the switch using the circuit tester, check for good ground.

Pull the connection at the head light and using the basics that I have given, run a hot and a ground wire from the battery to the head light bulb connection and  carefully touch the wires to the bulb. Dont let the hot or neg wires touch at any time. Not that hard just be carefull. Tell if me the bulbs work or not.

Back on tonight...

Suzuki electrics are a bit wiered, the switch
actually grounds the circuit, so all the wires
show hot 12V when tested.  Make sure the
grounds are good, as in a Suzuki, these are
almost like the hot wire in most vehicles

Check your bulbs and make sure your not
chasing a simple solution

gary_hill could you send thoes diagrams please thanks alot.

Could be a bad turn signal switch also.

Good point, Wild. My limited electrical knowledge came from years of "customizing" American electrical systems.

Trizacker, look at your over all wiring under the hood and dash. Wires that have been "hacked" into the factory loom may be causing your light problems. Try removing or disconnecting any new "hacked" wires one at a time and then check your lights .  Also check to see if a trailer lights "pig tail"  has been added to your tail light wiring...you have mail...Good luck,Gary

One thing too, if you don't have one, pick up either a Chilton or a Haynes manual, they are lifesavers.
