I just put a brake controller for towing in my 98 K1500. Looked up to connect the brake switch wire and not only can I not get to it, I don't know wich wire to connect to. There is a lot of wires. I'm used to just 2.

 

Does anyone know the best way for this or should I just run a wire back to the tail lights?

 

Thanks

On my 98 K3500 there's an electrical panel under the dash to the left of the brake pedal. Bottom left of that panel there's a connection port for the TBC: power/ground/brake light. I think the brake light/switch wire was light brown, but not sure. Easy to test with a test light. Works great for me, your truck is probably the same.

Your right. Thanks. I'm used to Fords with the 2 wire brake switch. This works out great, cause I hate cutting factory wires!

 

 

 

 

Can you tell me what kind of connector you used to connect the brake wire to the pin in the block? Thanks

I just used a spade terminal soldered on the end of the wire. It'll plug right in. You MAY be able to find a factory plug, but the spade terminal is easy and I have a bunch laying around. Good luck.

Thanks for the info. That is what I had in mind also, just was not sure it would work since the pin is so small.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
