How to splice

How do I splice the bumper mounted turn signal connector to the wires? What color/gauge and what wires go to which wires. 2001 Toyota Tacoma

 

Show the rest of the aftermarket turn signal, Black should be ground but I don't know why there's two positive leads unless it's a switchback for running lights.

 

White-black is ground
Green-yellow is 12v+

You will have to figure out the wire colors on the aftermarket light

 

Black is ground, yellow it signal, & brown is running lights. Is the other side of the aftermarket light Black, green, brown?

 

I mean you can just tie the grounds together then just touch the other wires to the positive lead on the truck to see what one lights up the bulb....
Then soder and heat shrink them together, maybe wrap some electrical tap around them afte is to just to make sure you keep the connection clean

 

Red is hot
Black is not

 

Black to ground, yellow to left brown to running and green to right. 14ga wires, solder and heat shrink should give a splash proof connection. Crimp connectors will work, but tape the gaps. They make a crimp connector that doubles as heat shrink as well.

 

A $5 dmm will tell you the rest.

 

These Posi-Taps are totally awesome. . .You can get them elsewhere, but Crutchfield was the simplest place I found:

Hey! I had the same issue as the OP. I ordered the replacement socket that had the 3 wires (same as OP) and some posi-twists to connect the socket wiring to the harness wiring. I have the black wire on the socket running to the white wire from the harness, and the yellow wire from the socket running to the green wire from the harness (only 2 plugs come from the harness). It worked when I first tried the signal, but the signal was still going super-fast as if a light was out (I checked, and none were).
For good measure, I tried connecting the brown to the green, and no dice. So I went back to the green-yellow connection, and now it won't signal at all, rapidly or otherwise. And ideas for a newcomer like me on what I may need to examine more closely? All bulbs everywhere are good. Thanks.

UPDATE: connecting both the black AND the brown wires from the pigtail to the white wire from the harness seems to have fixed it.

 

what tools are you all using to shrink crimps

 

that’s what I have. Blasts the area melting everything else like my hand and switch the crimp is next to and requires an outlet not always accessible. Can’t be run off the bed.

 

Blast from the past!

All connections I solder and heat shrink to those larger then 8AWG for the most those get crimped on lugs.

 

Time to ditch the cord

thanks
Always leaned towards Milwaukee working on cars having lots of their tools and already having batteries + charger

probably gonna get a small butane pen style precision heater/torch
As they have a curved shrink tube tip, are small for precision, mobile and refillable
Tiny tool, and much cheaper
Buddy also working on cars swears by his

 

The butane ones are nice for the smaller stuff. But since you’re team red: https://www.homedepot.com/p/Milwauk...VQgh9Ch3-YA2aEAAYASAAEgLOL_D_BwE&gclsrc=aw.ds

 

thanks
I’ve had a heat gun
Cordless only changes power cord
Gonna try a butane one. Not only cheaper
But assuming it has the same 600deg required
Small case. Fits anywhere even doing underneath dash work. Without excessive heat flying everywhere on surrounding parts like a switch, my hand, etc

 

I tried one of those butane small torches might have been the brand.

Might have been 10 years ago or longer,

I can hope they have improved the one I had was junk used it a few times it is around some place.
