The blue wire is the wire to supply voltage to your "running" lamp filament in the buld. Take your bulb out and look at the back side of it. It should have two round connectors on it. One is for the turn signal and one is for the running light. The "running light" should be on when you start the bike. When you turn the turn signal on on that side, the turn signsl filament should light up along with the running light filament.

With the bike running and headlight on, all four turn signals should lit as "running lights". Earlier models did not have the "running lights' on them. Now, when you turn the turn signals on either side the bulbs should blink much brighter. If you press and hold both the right and left turn signal switches, you're four way flasher signal should come on. If you still can't figure it out, Drop me a line at and I will scan a wiring diagram in for you and send it to you. Good Luck Steve

    If you can find a Clymer's manual for your year model bike, it would have a schematic drawing of your electircal system. Remove the lens of one of your turn signals. Take the bulb out and see if there are one or two contacts in the socket and on the bulb. There should be two if your bike is equipped with running lights. Now, if you purchased the bike used, a previous owner may have swapped the turn signals out with earlier units or they may be aftermarket units on there now or in the past. There are also some differences between the "domestic" models and the "export" model bikes. The Clymer's manuals have wiring diagrams for those models as well.

    It's funny, when I was in the motorcycle repair business, I used to them people that I couldn't fix a bike over the phone now here I am trying to do it on a computer. LOL. If you want me to scan a wiring diagram in for you contact me at my e-mail address. wd4ity @ Leave out the spaces. Good Luck , Steve

How to fix my tail lights, my head lights work,brake light works and turn signals work, dash do too

Maybe a broken or lose wire. The turn signal and brake lights operate from one wire and the tail lights operate from a separate wire. It is possible that the tail light elements burned out of both bulbs. Pull the bulbs out and check them first.

I had the same problem on a 92 & 95 Dakota years ago, replaced the turn signal switch in the column & found a loose ground wire in the harness back by the tail lights. Never had a problem again. If you're gonna try to replace the switch you will need tamper proof torques bits just FYI. Good luck. Let us know how it turns out.

1993 chevy silverado parking lamps go of when i turn on headlights, signal lights flicker when i press on brake.

Yes I would look for a ground circuit problem. I would look at the ground wires for the headlights first. Even run a new ground wire for the tail lights to see if it helps.
Could be a ground connection for the body to frame or body to battery.

I have a utility trailer with no tail lights. I have two new tail lights with two wires each. companys name is Blazer 12v stop/tail/turn can you help me hook them up please?

The new tail lights will use bulbs with two filaments. One is brighter than the other. The bright one is for brake lights and turn signal. The other one should light when you have your car's parking lights or headlights on. One wire is is for each light, but a third connection is required. This is the normally not another wire, but is the bracket of the taillight connected to the the steel frame of the trailer. If this is a welded trailer, then you can use the trailer frame, but if it is a bolted together trailer frame, and is is not new, they you will be well advised to run a third wire, which you should connect to the mounting bracket of both light fixtures and run to the connector that plugs to the car connector. You can use a 12 volt battery, such as from a cordless drill or a car battery to determine which original wire (plus the bracket of the light fixtures) will give you the bright light. Now you know which wire on the new tail lights is which. Likewise, on the pig tail connector from your car, you have to determine which wire is for which turn signal, (one for each side) vs. the parking lights/headlights (shared by both sides). The common wire is usually physically distinct. Simple pigtails have only 4 wires - left, right, parking, common. I hope you found this helpful. Good luck Al K

Lights not working

not likely, the flasher relay doesnt control headlamp.Check ALL fuses,and ALL the bulbs .Make sure head lamp works if you give it power using seporate wires to test it,if it does and using high and low beam make no difference check headlamp ground wire.Cool?

I'm trying to replace the tail lights on my motor home which is built on a for econoline chasis (1988) when I took the old ones off a lot of the wires were pulled out of the assembly or just rusted off. ...

Reconnecting a 7 wire circuit.....I presume you have located the rear JUNCTION BOX, or HARNESS splice.... At the lights wiring.
1. YELLOW = LH Turn signal
2. RED= STOP Lights
3. WHITE= Ground
4. BLACK= LH Tail Light/# plate lamp
5. BLUE [If available] Auxiliary Power Supply
6. GREEN= RH Turn signal
7.BROWN=RH Tail Lights
Depending on style you may find that the LH and RH Tail lamp colours are the same.[ie] Both Brown or both Black.
Best of luck in your endevours.

Tail Light Malfunction

Try looking for the spot where all your wires come together, near the rear bumper. I was having the same issues until I found the problem today and fixed it. I found a loose ground to the frame the bolt holding multiple grounds was loose. I found it near the rear bumper. I tightened it up and everything started working correctly. Good luck, hope you can find the problem.

Tail light problems

Probably because it blows immediately because the short is now a dead short. The hot wire is completely against the ground not just rubbing. Has the car been hit in the back at any time? Look underneath and see if any wires are hanging down.around the tail light area. Your looking for a wire that is rubbing against metal . Could be inside the trunk behind the covers .
