Paired alarm and engine ecu
Paul does not have any. Already talked to him. For the life of me I could not remember Will Tillery. I will shoot him an email. Thanks for the reminder.

As long as the Alarm ECU is active you can usually slap in a new ECU without having to touch the green Alarm ECU under the passenger side dash. I've done it many many many times. It's only when you get an ECU out of a P38 that is not setup for the D1 Alarm ECU that you usually run into a no start condition = T4 programming time.
I have swapped ECU several times and no issues also. But out of the blue the truck won’t start. Hooked up my lynx and had a code that the ECU has not received signal from alarm. Key fobs don’t work and have solid red light on dash. I can’t even connect to the alarm ECU with the lynx.
I had that once and I replaced the green alarm box with a spare I grabbed out of a junk yard vehicle and was good to go. When I was using the lynx on the original unit it apparently lost communication during programming and made the original totally INOP. I honestly DO NOT touch the lynx alarm programming anymore. I'll program a remote, but I will not try to config the alarm box options anymore. Not sure if it was a glitch, or what, but those green boxes don't grow on tree's anymore.
Yes I have killed a green box with the lynx before. I never do anything security except remotes. I think there is a bug in the programming for it. I think this time the alarm box just failed on it own.
