Turn Signal Wiring Help - Painless

[gb043075]

Thought I was making pretty good progress, running / head lights working good (with the exception of no park lights - only full lights but I'm pretty sure that is my old switch I'll deal with later). I am trying to hook up the turn signals and bypass hazard lights completely.

From the stock turn signal switch, I have two GY, two GO, a GW, and a G green (wiring schematic I found from Coolermans site says that should be GL - green blue but I'm assuming my green is green blue).

The painless harness provides the right and left rear, right and left front, a power wire and a brake light wire. So I have both right front and rear connected to one green yellow and the left front and rear connected to green orange. The G is connected to power source from Painless (purple wire) and GW is connected to white brake switch wire from Painless. When I engage turn signal all lights flash including headlights. I tried wiring front and rear separate to each of the individual GO / GY wires but it had no effect. Also tried several variations and a few hours with multimeter to no avail.

I also have a brown emerency flasher B+ wire provided in painless kit. Not sure where to put that or to dead end it.

Any suggestions as to how I can bypass having a hazard switch (can I?) and if so what am I missing. What would make all lights including headlights flash?

To review the headlight switch hookup, I again don't seem to have stock color wires. Coming out of what appears to be my stock light switch, i have R, RW, and two Green. The two green are not hooked to anything with red being power source from painless kit and the RW hooked to park lights and dimmer wire. Also tried multiple variations in that setup with no success other than as wired.

Thanks for any input.

What year model are you grafting the painless to??

 

[gb043075]

72 FJ40, built 12/71. Thanks.

I'll check my painless install if I can find a flashlight......

 

[gb043075]

another clue / mystery is that when headlights are on, no flashing when signal is engaged. Guessing it may lead back to my headlight switch wiring and the two unused green wires? I originally tried connecting a green to the running lights per Coolerman wiring diagram, but no juice to park lights, only headlights. However, it does solve the headlight blinking problem, only the typical hazard lights (turn signals and side markers blink) in that configuration.

i can't tell too much in the dark so I might have to look tomorrow.....
I can see:
GY hooked up to a Green painless wire
GY hooked up to a Blue painless wire
GO hooked up to a Yellow Painless wire
GO hooked up to a Light blue painless wire

I can look at it better tomorrow......

Mine work perfect but I remember beating my head against the wall trying to figure it out.....I'll do what I can to help with it when the sun comes back around......

Thank you! I just hooked up that configuration and I am one step in the right direction. Now when I engage right turn signal, all lights blink with exception of the right front turn signal (and no headlights because I rewired light switch to include green as mentioned above, which means no park lights, no park lights even at all lights on). Opposite at left turn signal.

Man I love wiring

 

[ocdbeetle]

I'll see how my running/headlights are hooked up too.....

When I switch to "parking lights" my front bib lights and rear running lights come on.....

When I switch to "running lights/headlights" my bib lights go off, headlights and rear running lights on....

ok, getting closer - i have no juice on either green wire at parking light setting (switch half pulled out). So, I've wired parking lights in with dimmer lead and have full lights at full switch (all the way pulled out). signals are working well. One problem. I have two wires to each rear corner, one for turn signal, one for tailight. I think I've narrowed down that that was my problem, I had them tied together since I need my tailight to serve as both. I have not wired in my brake switch yet, is that the missing piece here? If i connect the painless brake switch power and brake switch wire i get brake lights but only when lights aren't on. Lights on i get nothing. I guess my last remaining issue on this lighting hookup is how to run the rear tails as lights and brake lights. Or maybe that's why they have reflectors beside them?

Update - Get brake lights with lights on making contact with brake switch - I'm guessing no tailights is correct? Please forgive me for typing out loud (and for being a newbie idiot) but I'm going insane with this stuff. I plan to write all this down and post it for the next painless customer.

 

[gb043075]

Everything seems to be in working order with exception of taillights. As it stands, front and rear turn signals work fine, but the tail lights don't light up with headlights on, they work only as signals and brake lights.

I have two wires in the painless kit, one for brake lights, one for tail lights. If i wire both to the rear taillights I get the crazy all lights flashing scenario.

The tail lights SHOULD function as both taillights and turn signal / brake lights correct? As it stands I have only rear side marker lights and my reflectors serving as rear end protection in the dark.

THanks.

The tail function uses one filament(dimmer one) the stop and turn work together (the brighter) filament...

 

[ocdbeetle]

make sure you have a two filament bulb......sounds like you've got it about figured out.....

 

[gb043075]

Yes, they are dual filament, they are new replacements (housing complete) from CCOT. I took a look to make sure. Will call painless tomorrow and see if they can help.

Thanks.

79 FJ40 and the very painfull(painless) wiring harness.

I'm trying to figure out where I went wrong. Here's what it's doing:

With the parking lights on only:

front right - park light on and turn light on dim.
rear right - tail light on and turn light on dim.

hazards on only:

right front - park light and turn on dim
rear - normal

turn sig only:

right front - park light and turn on dim, blinks 2 times then stops
rear - turn normal

The left side of the truck works right.

 

[kelly148]

I just finished taking a part the front and rear harness to check the wiring. Nothing is connected wrong. Now I'm taking the dash a part. I fracken hate painless!

 

[DSRTRDR]

do you have the Toyota FSM for your year truck ?

for the stock switches to work properly, you need to recreate the circuit for the brake, hazard and blinker lights - direct connections between those are not included in the Painless kit

GM style switches (which is what Painless builds for) work differently than Toyota switches

 

[kelly148]

I made jumpers for the painless turn and haz flashers. I'm using the using the stock switches. I can't find how power is getting to the right turn side of the harness when the parks are on. I just pulled the fuse panel out can't find anything wrong there. I must be missing something...

 

[DSRTRDR]

it's not at the fuseblock, it's the connections between the switches, and the ground at the lights, or the dimmer switch (that gums up easily if you don't have the plastic cover)

the side marker lights often do not ground well, since the bezel around them can rust, and it sits on paint anyway - you may want to run a wire from the screwpost inside the fender to a better ground

you don't say what year your truck is, so I don't know whether your blinker lights could also have grounding issues

 

[kelly148]

it's a 79. I'll try a different ground. Everything is new on this, so rust is not an issue. I have run all new grounds.
