I know this should be simple. But they won't come on.
If I run a hot wire from the battery to the red wire going into the backup light socket, both lights will come on but that is the only way I can get them to light.

I checked all the fuses and they are all fine. Which one is for the back up lights ?
Do the lights run through a relay ?

Where is the back up light switch ?
I found a connection on the top of the transmission kind of towards the driver's side near the front. There are two wires coming from it. If I disconnect these two wires from a connector up the line somewhere and put power to one wire and a test light to the other, the test light will not light no matter where the gear shifter is. If this is the backup light switch, am I correct in assuming that it doesn't work ?

If I go to the other side of the connector up the line somewhere that I have just taken apart and put power to one side, I get a spark (obviously a ground.)
When I put 12 volts to the other connector, I hear what sounds exactly like a relay click somewhere on top of the carb !

Does anyone know where :
1. The fuse for the back up lights is.
2. The backup light switch (which I assume) is on the transmission.
3. Where do the wires from the back up lights in the rear bumper run to ?

I'm even more confused than usual and that's sayin' something. Any direction anyone can give me would be greatly appreciated.

I don't want to just run a new wire to the sockets and hook up a manual toggle switch on the dashboard because I know I'll forget to turn the stinking thing off but that seems like my only option.
Help? Please ?

Back up lights

The back up light switch is on top of the transmission....the one close to the motor.....when you put the trans in reverse it makes the switch and the lights should come on....I pulled my wires into the first time i pulled the transmission....so i put a switch on the dash to turn back up lights on and off

It appears that there are two switches on the top of the trans. The switch closest to the motor doesn't have a connector plugged into it and there are no unplugged connectors hanging around anywhere.

The switch a little further back is the one with the two black wires coming from it.

I wired up a toggle switch on the dashboard until I can get this sorted out but I really hate Mickey-Mousing things around when they should work properly in the first place.

I wonder if someone pulled my trans at some point and broke the connector and just cut the wires and taped them up someplace ?

Thanks for your help,
Dave

The rear plug is for the 4wd light in the dash... when you pull the t-case out of 2H and into either 4wd gears the light comes on (if you had it plugged in. The other end of each plug goes into the wiring harness just above and to the passenger side of the coil. There are two connectors that are opposite so you don't swap the plugs by mistake. You can still get either of the trans switches from Suzuki or source them from Petroworks or Hawk.

My reverse lights aren't working either. I unpluged the switch lead in the engine bay and crossed the wires and I had reverse lights, so now I know I need a new switch.

Like everyone said the closest switch to the engine is the "reverse switch". The wires (one RED / one Yellow) run to a connector the is in the engine bay attached to the fire wall about center of the vehicle.
You can buy a new reverse switch for about $20ish from Suzuki Depot (website not working right now).

Here is a wiring diagram (the reverse switch is not labeled but it is the middle one of the three in the diagram).

Good Luck !!!

I think the switch you are describing (the one closest to the engine) is the switch that has nothing running to it (on my trans.)
The switch a few inches behind it is the I mentioned previously that has two black wires running to it.
I cannot find a connector that has a yellow and red wire anywhere near the front switch on my transmission. Am confused.
I hooked up a toggle switch to the dashboard and ran a new wire to the backup lights but I know I'm going to forget to turn it on and off. It's trouble waiting to happen.

Well, thanks a lot for your help guys. I sure appreciate the advice,

Dave

The tail coming off of that switch (on the trans) is normally about 3 feet long. If it was torn out during a trans replacement you may not find it as it may have been tossed. You can find where the tail is supposed to be plugged into up at the top center of the firewall on the main harness (left of the coil).

Billjohn, somebody should dub you, "Samurai Master" 'cause you clearly know your Suzukis.

The pigtail for the wiring loom was exactly where you said it was and there's nothing attached to it or nothing anywhere near it that looks like it should be attached to it.

I think I'm going to try to pull the backup light switch out of the transmission and see if I can fabricate some kind of plug to fit into it to go to the proper pigtail on the firewall because the proper wire is long gone.

Thanks a lot to everyone for their help and advice,

Dave

Glad I could be of help.
Although Samurai's are not sold in the States anymore, you would be surprised at how easy it is to still get parts. The link above was one possibility, but if you can't get through there check out PetroWorks
You can still get those switches for the top of the trans.
