Re: LS factory cruise control hook up
yes it drops to 0v when pedal is pressed
and if i unplug the connector from the cruise module that faint hint of brake light disappears |

Re: LS factory cruise control hook up
I have to leave for work now, but will check in the morning to see if mine glow any at all, but don't think they do. I'm leaning towards something being messed up in the module since the wiring seems to be correct and unplugging it makes it go away. I'll let you know what I find in the morning.

Re: LS factory cruise control hook up
so a friend of mine gave me the idea of running a diode off the g wire to the junction at the brake light wire.
http://frys.com/product/1799257?site...H:MAIN_RSLT_PG this would essentially make that 9/10v stay only on the G wire and not impact the brake light wire. this way the faint brake light illumination would stop but when I press the brake pedal and it sends 12v to the brake lights it would also send 12v to the G wire back to the cruise module. so that I think would solve the brake light issue but still doesn't help figure out why the cruise control wont work |

Did you tell us your tail lights were LED ?

I have 2 questions on this.
1. I have all LED's but with the relay mod it should be fine correct? I also have the grounded flashers in place will this possibly make it work? 2. I don't have speedometer cable, mine is a GPS speedometer. Their is no cable attached to the trans at all. Will I need the cable to be hooked up? I want and try to have cruise for the 2016 HRPT since I didn't have it for the 2014 run. ![]()

Found a 4 wire replacement handle.
$44.99. I think a junkyard will be a lot cheaper! ![]() http://www.classicindustries.com/pro.../dd100102.html

2 You won't need a speedo cable, just a VSS wire coming out of the PCM. 3 That switch will work, but it will require several relays to reverse the switches inside of it.

Re: LS factory cruise control hook up
It will, but there are several relays required to change the normally closed switches inside of it to normally open like a GM switch.

So here is my crude wiring diagram
Hopefully we can figure this out. It would make my weekly 250 mile round trip drive a lot nicer. Posted via Mobile Device |

Re: LS factory cruise control hook up
with the key on and taking readings at the module with the connector plugged into it im getting these readings
a- 0v (toggle switch is in the off position) b- 0v c- 0v d- 12v e- 0v f- 12v g- 10v h- n/a j- 0v k- 9v also I forgot to include that I have an inline fuse wired in to the power wire right before the bottom split on my diagram I also picked up a 12v zenner diode this weekend that I have yet to wire into the G wire to get rid of that voltage going to the brake lights until the pedal is pressed. |

Re: LS factory cruise control hook up
so just wired in the zener diode to the G wire so my brake lights are not affected by the 10v being sent from the cruise unit.
just re-tested to confirm everything is in complete working order key on, engine running, connector unplugged to test leads: A- off position - 0v A- on position - 12v B- (with A still "on") 0v resting; 12v momentary toggle down pressed C- (with A still "on") 0v resting; 12v momentary toggle up pressed D- 12v resting; 0v brake pedal pressed E- 0v (ground) F- 12v regardless of toggle A position G- 12v brake pedal pressed H- n/a J- n/a K- 11.6v |

Re: LS factory cruise control hook up
Everything on your diagram looks to be right. Have you tested it with the diode installed? The only thing that looks odd on your diagram, and I don't think it would affect anything, is your brake lights appear to be wired on a key on hot wire rather than a constant hot. I assume you are using an aftermarket harness and wired it this way?

Re: LS factory cruise control hook up
If you are talking about the relay diagram in post #7, then it should work, although I have never personally tried it.

they are in fact wired to the proper fused brake light position and i get brake lights with key off too. sorry about the confusion. so if everything is wired correctly then i can only assume its the box itself? i call the local LKQ and they didnt have any 99-02 silverados available so ill keep calling around tomorrow. does the yard local to you have one readily available? |

Re: LS factory cruise control hook up
There are 6 pick a part type yards with in a half hour of me, and they almost always have some 99-02 trucks in them and the cruise modules are almost never taken off, so I'm pretty confident I could find one.

Re: LS factory cruise control hook up
I can barely read that! Can you make it bigger please ? Haha
I am glad you figured out out because I will be doing similar in a couple weeks and now I have an awesome example to work from if i have any odd issues. -IZZY
