Just had a remote start, passive keyless entry, push button alarm installed. Everything works great, except the remote start keeps trying to start the car even after it is running. Tech support said I need to attach a wire to the tach to prove it was running.

I had a professional installer do the install, and think he just didn't know what wire it was. I'm hoping to go back tomorrow morning with a solution and wire for him to hook up to.

Any help would be greatly appreciated!

 

Pink wire is tach

Ignition is black.
