Installed one on my truck a few weeks ago.
Followed instructions ( exelent instructions including pictures ) would have taken about an hour but I re located the timer switch to the steering wheel cowl ( more convienient ) so it took a little longer. Every thing fit, everything was included, no bs, no hassels. works like a charm, you dont have to wast a lot of time baby sitting the cool down.
You set the timmer, shut the key off, lock the doors and when it times out it shuts off. If some one breaks in while it is timming and hits the brake it shuts down immediatly, if you also turned on the kill switch when you set the timmer it cannot be restarted even with the ignition key untill the kill switch is turned off. You can also turn on the kill switch and crank the engine to do diagnostics or to prelube the engine befor starting. It is a great add on, adds on some security and time saving convienence. Wonderful for emergency pit stops while traveling>> no waiting for a cool down <<<< Next greatest thing to a DTT tc & vb
If you care to build your own you can do a search on cool down timers, several members have posted the circuits and material lists.
just my $. 02
