Hi,I'm getting ready to install a brake controller on my 99 4Runner Limited V6 and been searching here for the location of the brake light switch.difficult location to add a wire.is there any other location that's easier to find the brake light switch wire (green/white I think)so i can connect the brake controller.today is rainning but I will try to get it done tomorrow because going to pick up a camper Monday.please Help

 

Unplug the connector at the brake light switch you might need to cut some cable ties or some tape .

Now I have enough room to splice a wire.

If that is to much work behind the plastic kick panels on the left and right sides there are some connectors find your Green/White strip wire.

Always double check with your meter you do have the correct wires

 

thanks,that's what I was thinking about the kick panels,I'll try that route and see if I'm successful

 

Not sure if your 4Runner is the same but that was the biggest pain in my 98 Tacoma. Laying on my back under the dash, working to separate individual wires enough to test and splice into one.

I bought a wiring kit from etrailer and it came with the crappy quick splice connectors. Not ideal but the easiest way for sure.

I had to cut the electrical tape wrapping closest to the plug so I could get enough room to get a wire separated out and splice into it.

Having a helper...helps. Hard to poke a current tested into a wire with one hand while holding down the brake pedal with another to make sure you've got the wire that's active only when the brake is depressed.

 

yes it was a big pain but thanks to Wyoming9 I looked behind the kick panels and found the correct wire with a tester.a lot easier that way than under the dash all the way up there.I got mine from etrailer too and I'm not convinced about the crappy quick splice connectors either but it was the easiest way.maybe later on I'll replace the connector with a better one

 

Vampire connectors should be outlawed in the automotive industry, it wouldn't last 1 winter in Canada. Solder the connection when you get a chance.

 

I agree with you and I will solder it soon

 

Funny thing is, my 1991 Bigfoot camper (made in BC, Canada), is chock full of quick-splice connectors.

I completely agree that they're crap, but they're regularly used in the RV industry, and the ones in my camper anyway are doing fine after 25 years.

Even still...I wish they had used better connections.
