Done. One of the main things that bugged me when I installed it before was all the left over wires from the Viper... I had a ton of unused wires and it left me wondering if I missed something, hence the R/S not staying running...2011 F-250 Super Duty

If you really think the info you have will help me get it in and working let me know because the Alarm is currently on eBay and with two days left the bidding is not far from hitting my reserve now and I want to end it before it hits the reserve. thanks2011 F-250 Super Duty

you would have to be the judge of that, however the info forwarded is pretty much a step by step. just don't forget to test the wires.Ted

OK, I ended the auction and plan to give it one more try this week end. wish me luck and thank you again Tedmond.2011 F-250 Super Duty

Does anyone know exactly what voltage the viper is looking for, for the tach wire? I can't get to the injectors on this EcoBoost so I was wondering if I can use the feed for one of the coils... I have three wires going to each coil, one is 12v when it's running, the other fluctuates from .12 to .50 as you rev the engine so I am thinking this may work for my tach wire.

I went on Xpresskit's site and tried to find an answer under support but I couldn't find anything. I'm hoping one of you guys know. What does it mean when the LED on the PKTX does "2 flash then pause" over and over?2011 F-250 Super Duty

It's back in the truck except this time I am focusing solely on the remote start first and not messing with all the other stuff. It didn't take me long to get it back in (I'm getting pretty good at this in and out crap) and I've verified all the wires and unfortunately it won't remote start unless a key is in the ignition. With a key in the ignition (off position) it remote starts and remains running (I was able to pull a tach signal off a coil) Take the key out and the R/S goes through it's sequence but the starter doesn't engage. the ignition comes on and I can hear the on-board R/S starter relay engage and I verified 12v is being applied to the starter side but the starter doesn't do anything... So I have to figure this out. I'm also not sure if the PKTX is programing. It doesn't give any kind of indication whether it's programmed or not... I can program it and one time it will give me 10 LED flashes and then nothing and the next time I try to program it, it gives me the 2 flashes pause over and over. None of the LED's on the bypass come on during the R/S process which I find odd. I don't think this thing likes me. 2011 F-250 Super Duty

Here are my exact connections. Can somebody please look this over and see what, if anything is wrong or incomplete? All the connections at the ignition switch and transponder are soldered so I can't see there being a poor connection issue here. FROM VIPER TO TRUCK, R/S HARNESS 10 PIN Orange to PURPLE / green Pink to ORANGE / White Purple to Blue/White Starter side Green to Blue/white Ignition side RED / White to Battery RED / Black to Battery Red to Battery VIPER MAIN HARNESS 12 PIN Red to Battery Black to ground Viper H2 HARNESS 18 PIN PURPLE / White to Coil (Tach Signal) BLACK/ White to Ground (Neutral Safety) Dark Blue to Dark Blue on bypass (-Status input) Brown to PURPLE / White (+ brake switch input) PKTX CONNECTIONS (From bypass to truck) PURPLE / White to PURPLE / Gray at Transponder plug (RX) Yellow/Black to Yellow/Black at transponder plug (TX) Pink to PURPLE / Orange (Immo Power) As I said earlier, the Starter does not do anything unless a key is in the ignition in the off position. It remote starts fine and stays running with a key in it... Take the key out and the R/S goes through it's sequence but the starter does nothing. 2011 F-250 Super Duty

All looks right, I don't see keysense listed..Maybe thats the problem? Wrap the key head in aluminum foil ( shiny side out) so that the matal key blade is the only thing sticking out(to block the rf chip in the key). This will tell us if it is key sense or a bypass issue. There is a 2nd status out you can use on the viper (blue/white - ) (must relay to positive if using a positive key sense wire).To master and control electricity is perfection. *evil laugh*
