03-04 tundra 7blade wire identification

I need some help with this before I have a stroke. I have an 03-04 tundra cab and a half that has the 4.7 v8. It came with the 7blade tow package but it has been broken off. I need help identifying which color wires go to which position on the new 7blade.

 

Can you post pictures of what you have currently and what you are trying to install?

 

Below is good explanation with list of wire colors. I'd probe each wire with a 12 volt tester.

I'll post some pictures when I get the chance. I don't understand where the purple wire comes into play because it isn't on the truck. For the plug that has the 3 wires, the colors are blue, black, and white.

 

This is what is going on the truck. The old one was broken off.

 

I haven't checked tundra. Could be rv standard so no purple. Best to test each wire.

 

Can you get a pic of the wiring on the truck side that you have as well?

 

I'll grab a pic of it tomorrow when I get back to where it's located

 

These are pics I used when doing my 04. According to EWD, 03 wire colors are same.

Important to note - trucks with the towing package will have the wires/colors with the *1 next to them.

 

This is easier.

Look up behind the bumper, unplug the old one, plug the new one in, and screw it back in place.

 

Anything plug-and-play is awesome, too many people do a shit job or use harmful stuff to splice harnesses out back. I've cut other people's crap off one too many times.

@ OP, Whatever you don't don't use scotch-locks or t-taps to install this stuff if you need to splice or tap things. There are way better solutions out there.
