And if you want to see more pictures more we recommend the gallery below you can see as a reference from your Retrofit Gm Cruise Control Wiring Library At Rostra Diagram. Most of them, such as cruise control switches, clutch switch, and brake switches, may already be in your car. Here is what I have in mind, and check my math here. Even when the signal wasn't adjusted before being sent to the ecm, it often was changed in the ecm to a multiple of 1000 pulses per mile before being sent to to cruise and speedometer. Newer cruise control systems abandoned the vacuum actuator for an electronic module with an internal stepper motor to pull and release a throttle cable to maintain vehicle speed.
While most of our customers install these aftermarket kits themselves, we recommend professional install of this cruise control system. I recently installed a cruise control that was purchased from. Not every warehouse stocks all the same parts, so the closest warehouse to you that has the part in stock is where your order will ship from. Dakota digital makes a 8k pulse per mile 8 pulse per rev generator, but does not make a 4 pulse unit. Make sure to mark the steering wheel position relative to the shaft before you pull it. Many fwd cars using tone rings on the trans output shaft and magnetic sensors use this design. These modules require 12V ignition, ground, cruise control switch signals, brake switch signal, clutch switch signal, stop lamp switch signal, and a 4,000-pulseper- mile vehicle speed signal.
My only concerns would be the same as yours. I think that sums it up. Please only post in this section if you have directions on how to do a modification, complete a task, or steps to take to resolve a problem. You can pay with Visa, MasterCard, American Express, Discover or your PayPal Account. I don't like that there is force exerted inward on the throttle cables either. Depressing the clutch switch removes 12V from the cruise control module pin D to disengage cruise control.
If using the 4000 the range will be off and it will limit the speed over as well. Now that my Delco cruise unit is verified, and I know how to wire everything, I just need to come up with a simple method of getting a 4000 pulse per mile signal to the cruise unit when installed in the car. Your hood will not close. The sensor was geared to turn 1000 revolutions per mile, so the signal generated was about 4000 pulses per mile. Great project Nick: Very good suggestions on some of the existing pulse generator options out there. This removes 12V power from the cruise control module and clear its memory. All posts in here are put up for all to read and gain information on how to do something to their silverado or sierra.
Modification of the intermediate shaft is also required if you are using the original gearbox. It may be possible without disassembly. You can set your desired speed by using a Rostra cruise control switch that is steering column mounted sold separately. Why spend time and money redesigning a circuit that works? The module expects a signal that turns this wire on and off 4000 times in 1 mile. It took approximately 2 weeks for delivery and I was able to pay using PayPal. Please use fuses where necessary.
The signal should be 5 volts while on and 0 volts while off. Pre-welded underdash mounts are included with all 1967-72 columns and are designed to fit your application. I then welded the part of the bracket from the Chevy truck that the cable went through onto the closet piece. Vehicles with the cruise inhibit signal require its use when installing the cruise control module in a retrofit vehicle. The bracket which hold the cable is made from a closet rod bracket from Home Depot - because I had one laying around. It should light your test light all the time unless the brake pedal is pushed.
You will have to use a test light and find the correct wire going to one of the large connectors for the pcm behind the glove-box, the wire you need to find will light up when the cruise control switch is in the center on position, and it will shut off when the switch is slid to the off position. A Female End Plug which connects with the ididit wiring plug is also included. If not using the original steering box, a shorter length column may be required. Pin G yellow is the N. First off your pulling on the cables at an angle. In this case its job was really easy. In order to post or to see photos you will have to by.
If you cannot identify one to suit your application, you could make your own set of dash or center console mounted switches. A shift linkage new or original is required for installation and will attach to the lower shift arm provided on the column. . When you have gotten everything mounted, installed and verified on the schematics that the switches and contacts are wired in properly, you need to take it out on a open road highway and test the cruise control to insure it is operating properly. Brake Switch: The cruise control module requires two brake switch signals. The gray wire would go to the cruise control select switch which also goes to the ignition cruise switch. I am still pretty sure that I need 4000 Pulses Per Mile, and maybe what I need to do is put an Oscilloscope on my 99 suburban to see what the cruise module is getting for a pulse train.
The driver may remove his or her foot from the accelerator pedal and the cruise control module overrides the throttle blade angle to increase or decrease vehicle speed. It looked somewhat cheap to me. To get the Arduino to give me a simulated 60mph 4000 pulses per mile signal I programmed one of the outputs to go High for 15ms, low for 15ms, back High for 15ms, and so on. The power window relay and cruise control were also powered off. You'll also want the female pigtail this connects to.
Pin K brown 4000 pulse per mile speed input. I believe that this is a self contained unit that only needs a square wave pulse input to detect and change vehicle speed based on button inputs. If you like the Wiring Diagram Collection in our web, please feel free to visit again and get happiness in our web. I'm not thrilled with this because it's ugly. I looked into the aftermarket kits like Rostra universal and Snake Oyl but I decided I could do an equal or better job myself for less money. Also, the factory cruise interlock below about 30 mph would be halved. Any way the product works smooth at Hwy speed 55 plus, a Little jerky at lower speeds, maybe due to manual trans gear selection.
