Let us know how things work out.....

Can you show the switch and give a part number
Thanks for any and all the help

Switch it something you can pick up at radio shack any SPDT would work fine, I just like these cause I have used them in other places on the truck for my SPG and Backup anytime switch. They fit in nicely with the truck and most people think there stock switches. Just drill a single hole in one of the blacks and your good to go.

SPDT Paddle Switch - RadioShack.com

Here a pic of it installed next to the VSC button, well to the left of it, Oh this is when I was relocating my tow haul button.



Here a pic of the other swicthes on the dash to the right when I was test mounting my Storm into the charging base, I mounted it during my bluetooth AUX Mod but give you a idea of how the switches look else were.

Thanks the switches dose look OK.
Not sure about programming the PTR7 but thing I can do it with the information you have giving.
Be working this in the next couple days let you know now it go

Hi all
Not sure about programming the PTR7 so I was wondering if it could be hooked up to a 12 V battery outside of the truck and see if I can program it that way before I tear things apart in the truck just in case I can't figure it out.having trouble where it says feature at 9 10 and 12 need an option selected. Am I choosing delay on equals 1 or delay off equals 2?
Thanks

Yes you can power the unit up on any 12V source (extra battery, battery charger, etc.) I prefer this method to test things out.
You want to use option 12 and follow the directions. You need to program this time to hold the output to the VCS switch for 3 to 5 seconds should be good (5 seems the best). Set the delays as 2 no delay(blue), 2 no delay(white) and 2 no delay (orange) and for the outputs you can put 1 second (blue), 1 second(white) and 3-5 seconds(orange) and seconds from 3-5 should work fine but each truck maybe a little different. Hope that helps some, that way you get a 3-5 second timer on the orange wire (-12v) the other 2 outputs (blue and white) don't mater cause your not going to use them but it is easier to program them as 1 second just to make it a easy follow the program sequence.

That is completely different then you said at the beginning of this post. Your drawing said no delay with the output at 5 seconds. Which one is it? Please clear up?

Set the delays as 1 second (blue), 3 or 4 seconds (white) and 1 second (orange). Hope that helps some, that way u get a 3 second timer on the white wire the other 2 don't mater cause your not going to use them but it is easier to program them as 1 second just to make it a easy flowing to program it.

OK if I programmed it right when I put power it the ptr7 the red light on it should stay on for 4 sec.

Thats one sweet mod. I really need to do that. I hate pushing the VSC button everytime I start the truck!

Okay sorry my bad I had to go review my drawing and TR-7 manual again its been a while since I worked on this particular project, so forgive my mis-typing. I corrected the post above with the correct information.
By adding the 1 seconds delay would not cause any issues and for the timer output time of anywere from 3-5 should work fine to since its basicly anything over 3 seconds should disable the VSC. I would say for simplicity keep it at no delays and 5 seconds as I stated in the orginal drawing.

Okay if you program it right you should see the program LED light for the 5 seconds or what ever amount of timer you have it set for on the outputs. In this case we use the Orange wire as the output -12V to trick the VSC into thinking were holding the switch in for the 5 seconds.
So what you do to test it is to power the unit up by the red and black wire to the 12V source then trigger it by put the green wire to the positive 12V source too and then the LED will go on for 5 seconds then turn off. Or you can just tie the red and green wires together and apply 12V to them and the black wire and the LED will light for the 5 seconds and then go out.

Hope that this is a little clearer, sorry if anything I said earlier that may have been confusing but you got to give the old man a break since I have not worked on this in a while myself and don't keep the instruction in front of me all the time.

Guess if you really run into a problem programming the TR-7 unit you can PM me. You can send me the unit to program and test for you and I get it back to you just another option if you get really frustrated with getting it programmed up.

no I think to most people your instructions are pretty clear it's just that I know nothing about electrical problems or wiring I do think however with the information you gave me I am getting it figured out. Not only that I'm a old Fart trying to learn new things

Thanks very much for the help and patients for working with me. I just got in from the pole barn with everything hooked up and working correctly. When I start to truck the 2 lights come on. I can turn them off by pushing a factory button. now I get to figure out what's switch I want to put in there so I could turn it off. Thank you very much.

Damn, I don't turn my off that often but when I do now I just flip the switch and the truck does it each time I start it..

Oh no problem glad to see you got it all working now.... Radio Shack had a few other switches that would work okay too so you may just want to take a look see and what you may like. Just need to have commond pin and a N/C (normaly closed) pins and you will be all good to go.

[atvraptorman]

I know you have to program all three wires for delay but do you have to do the same for output? Also when putting in a delay after you pulse once and it conferms it what do you do? Pulse it once for every second? Is it just like doing the timers for the output?

[duanels]

I pulsed brown wire 12 times for Feature Number
2 pulse for blue option=delayed off
2 pulse for white option=delayed off
2 pulse for orange option=delayed off
1 pulse for blue timer (seconds in ones place)
5 pulse for white timer (seconds in ones place)
1 pulse for orange timer (seconds in ones place)
Used the Flowchart on page 4 of instructions
Hope this helps

sorry about the mix up make the 5 pulse on the orange not the white one
