Need wiring diagram. I have replaced the light harness but do not have a left side turn signal although the rest of the lights work.

Hi. Thanks for your question. For the diagram of Tail Light you can visit https://www.reliable-store.com and download the entire workshop manual. It has all the information along with the diagrams for better understanding. Good day!

With a test light check if you have power there with lights on and with lights off, compare left side with right side as far as location in the tail lamp plug for the tail lamp park lights.Trace the harness back to the left side underneath usual corrosion in this area.

under the rear truck there is a junction block with 3 harness
turn signals left side yellow wire
turn signal right side green wire
parking lights brown wire
you should find your problem could be the junction block itself look for water inside terminal at harness
hope it helps

Check for power at the light socket aswell as grounds

First and foremost, installing the wiring harness is not the easiest task, but not the most difficult. Typically you will use a 4 pole harness. One wire goes to tail light on, second wire goes to brake light, then one to left signal and right signal. You will need a test light of some sort in order to determine the hot or live wire for each bulb. Once you confirm the wire you can simply splice the wire off the harness into the factory harness. One thing I will mention at this point is using a typical four pin instead of a adapter that are a it more expensive can cause more draw on your cars electrical system. Although I have never had any problems on my cars. I have heard situations in which wires have become cooked.

As far as trailer lights go it may depend on the state. Here in IL, you can get away with running 1 light on each side of the trailer granted all functions work-brake, running lights and turn signals.

Good luck

Sounds like the converter is bad. Go to http://www.etrailer.com/faq-wiring.aspx and check the testing section. Hope this helps.

why not just replace the turn signal switch must faster and safer . buy one from your local parts house then you can see its not that easy to install but you can do it with a little help

What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.

If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.

Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.

If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.

But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.

This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.

Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.

I'm assuming you're just going to splice into the tail light wiring so that's what these wire colors are:
at the tail lamp 3 way connector:
black and yellow = park lamp
dark green and brown = left turn signal
there should be another connector with violet and black wire for reverse lights.
the stop lights are turned on through the turn signal circuits.
