I disconnected the module and still have to turn the key for the truck to start once i press remote start. I checked the wires on the ignition harness with a voltmeter. 1. Ignition 2. starter wire , then cut it and checked and the starter would not engage. So this is the correct wire. 3. Accesory 4.

I hope your not trying to power the vehicle's GREY key-sense wire. If not, did you inadvertantly re-program the flex-relay for anything other than IGN. Otherwise, it sounds like a by-pass issue.Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

Story - Phzzzt! Hey, what happened?! ... Isn't it obvious?

Moral - Never dismiss the obvious.

Well it is now working. I had the 12V for the remote start harness hooked up to ground instead of 12V+.   I want to run wires to my tailgate and would like to know for the magnetic solenoids if 20 gauge is enough?

I have an issue. If I tap from the remote start auxilliary output blue wire to the key sense the truck doesn't like it....

Thanks man 14 gauge it is then :)... I have another problem. When I have the alarm armed and go inside the house and come out 1 hour later and remote start the truck the oem alarm goes off...

This is because you don't have the keysense wire connected correctly. The keysense needs to see a ground during the entire RS process to turn the OEM alarm off....Mike M2

From the DEI it is the RS-OUT/5 Blue wire which is connected to the Key Sense wire which is the grey wire in the 2 wire connector on the left side of the ignition.   I am also using this BLue wire to send the ground to the PKT2 ground when armed..   Do i need to diode isolate these 2 wires?

 

use blue "status" for one and Blue/white "second status" for the otherKevin Gerry
