Hi all, Just browsing, but had some thoughts. Relays can be expensive, noisey, and wear out after a while, but sometimes they are what's needed. In this case, however, why wouldn't a 1k ohm or larger 1/4 watt resistor wired between the circuit (violet) and ground to simulate a breaklight and the cruise wired normally, at the violet? They can be had cheap at Radio Shack or someplace. The only issue that I can think of is that the the high side of the LEDs might not like being pulled to ground when the break pedal is up. I an't imagine that being true, but one never knows on these new cars. If they did have a problem with that, then a diode wired forward between the violet and the resister so the LEDs have a harder time "seeing" the resistor drain. In this case the cruise would connect where the diode and the resistor join. Anybody tried this? Alan

The resistor idea is not new. In fact, back in the old days when Rostra Precision Controls was known as Hayes Dana, they actually had a kit which included a high value resistor for just this purpose. The relay method is better. Quality relays generally are designed to last 100,000 cycles, so I don't think it will wear out. they only cost a few dollars too. The only down side is they make some noise when energized/de-energized, so they should be installed in a way to mask the noise. They can be buried deep in the dash behind sound deadner to quite them.

Another way to do the same thing would be to purchase a NC brake swith (the kind with an actuating arm) and let the brake pedal interupt ground every time you pressed the pedal. I used a NO button type swith for the brake lights. I used this method on a '67 Chevy PU that had the cruise in the ECM (6.0 LS1). John Spear at Speartech built me a new wiring harness and spec'ed out the cruise circuit.
Not being familiar with a Rostra unit, as I said, I thought violet was looking for 12V the way it was hooked up. I never it looked all the way through the column, to the rear of the car, through the brake light filament, then to ground.
Crazy idea, to me. |
