From what I remember the 3 way connector is for the front fog as well as the side light. It work appear that you have tapped off the front fogs for the LEDs and I would imagine the fog switch is turned on which is why the LED lights are working on what appears to be 'side lights'.

 

When you checked for voltage at the thee pin plug, one is a negative/neutral the other two are both positive (fog and side lights). You will need to keep the black in the same position and move the red probe. This will prove whether or not there is voltage when the side lights are on.

 

Kev

Im pretty sure the side lights stay on even with fog on or off... ill confirm tomorrow.

 

The one im trying to pull out is the one that has toyota in blue writing thta cable goes over it...Keron said he had issues with it so I dont feel as bad :-)

They were working originally, he had the dash out, then they started messing about, THEN he changed the bulbs.

 

If its just since the dash, then I'd check the plugs. Could be a dry solder joint on a plug, or simply not properly connected.

Good point, I missed that out of the original post.

 

As Listy said it could be a dry joint as the fuse and relay have been checked/replaced.

Have you checked for pinched wires on the part of the loom that plugs into the hazard switch?

 

Come to think of it the easist thing to do would be to remove all the panels again to check for pinched wires, then unscrew the hazard switch from the dash panel plug it in and retry the indicators.

Still not resolved yet, ive not had a lot of time recently but I want the car sorted by the end of this month...

 

I have been told that my head light is wired in incorrectly...this could be the reason why the indicators are flashing quick.

 

Please see picture.

 

At the moment this is how its wired...

 

1. Side Light (I did this myself because before there were no side lights!!!) This should be the fog...

2. Dipped Head light

3. Full Beam

4. Indicators.

 

Iky came around earlier and said that 4. should be the side lights and the indicators were separate and on the bumper. Since my car has an after-market bumper the indicators must of been removed.. I also thought that only face lift models had indicators on the bumper so never questioned that wiring of the current indicator.

 

I just need to verify that the above is correct as Iky has a facelift so could not compare it, once verified I will go ahead and buy some old bumper indicators / face lift ones.

Correct the pre facelift has separate indicators in the bumper. If those 5w bulbs are your indicators I still think what I wrote in post 33 might be the issue.

 

Yes mate it uses the same bulb as in the side repeaters (small ones), and not the type that is found in the rear lights such as brake lights.

1. FOG

2. Dipped Head light

3. Full Beam

4 is definitely sidelights.

 

pre facelift looks like this:

Pretty sure the pre face lift indicator bulbs are 21 watts. Might be worth looking at this first.

Summarise,

First car mod I did was changing the side indicators for clear ones and orange bulbs, i tested it then and they worked fine

 

Then after that came out the dashboard for vinyl and when i put it all back together I noticed the quick flash. All connections are properly in...

I replaced all bulbs afterwards but still the same issue...

 

I need to replace the indicator fuse but I'm having trouble taking it off. :-S

 

How did you test the indicators worked ok? Did you use the hazard button on test both sides individually?

 

Also do you still have the old wiring looms? If so you could easily test the above theory out pretty easily.

My fog lights come on as sidel ights for some reason, when I tracked the wiring back they have been wired through a relay and to the lighting circuit for the cig lighter and heater controls :shrug:

 

It passed an mot but when I re wire these up to actually perform as fog lights do I wire the 2 tiny bulbs up for side lights that sit next to the indicators?

 

Sorry for hijacking your thread btw ;)

I think I used the hazards mate, so I can not confirm that the indicators worked as I used the hazard and there on a diff relay :-(

I think I will edit that lol

Correct :) though you can also wire them into the original side light slot in the main headlight if you wish.

Now we are getting somewhere ;)

 

I'm pretty sure this is what the issue is. You need to fit 21watt bulbs or use resistors to stop the flasher unit thinking there is a bulb out.

 

Unfortunately the larger bulbs probably won't fit in the main headlights and so you will need to fit separate indicator units.

Just confirmed on my old pre-FL indicators. They are 21W.

 

Can anyone get me a pic of the bulb? is it the large type found in the rear brake and indicator lights?

Rather than me messing around with the wiring, is it possible to change the bulb in 4. so its a 21W of the same type of bulb?
