In all my years of remote starts in vehicles I have always found if it is a transponder key issue it will not even crank. Not for sure what to do till I get my hands on another OP500 to try some different options. If I could find a tach wire I could try to program it without waiting for a programmer. Thanks for your help though.

Dealer said there is no security on it but there is a harness with a DESS tag on it that is under dash. There is no ball and socket locations for one to go though. It just looks like a standard key. These are pics of under dash. Did you have any issues with the voltage sense not working? Have to change any setting other than crank? I just unplugged the DESS plug and it goes into a empty socket so it must just be there as a option.

And of course my OP500 disappeared last week and my distributor does not have any in stock. 😞 Does have DESS.

I am using a CM-900 and a Drone. The defender starts then shuts off after 25 seconds on all three attempts. The voltage before start up is 12.67 and while running is 14.45. I would have thought it would recognize this but it is not. I actually jumped from a running vehicle power to the module and ground to the chassis to isolate the power from a separate source. The vehicle connected was at 13.8 volts and the Defender stayed running with the separate power. This is why I am trying to find a tach wire to try. I tried at the coil pack without any luck.

Does anyone happen to know where you can find a tach wire on a defender? I put a remote start on a 2021 and it will start but does not like voltage sense and shuts off after 25 seconds and needing to see if I have better luck with tach. thx
