Hello I own a Caterpillar d6r XL 2004. serial aax00883.
What I want to do is install estops on this machine.
My question's are where does this circuit join in, does it stop a relay or do I install one, does it wire in to the ecm, etc. I have a copy of the schematic. just unsure where to start and what are the industry standards on this one.
cheers and thanks for your help

Just had a quick look and I think the easiest will be to wire the Estops in series, in a NC configuration with E308 yellow at the ignition switch.

With the engine running, disconnect E308 yellow and if it shuts down you should be OK using it. Installing Estops on machines which were not designed for them can log error codes when they are activated, but as long as you're aware of it, it's no biggie.

As far as industry standards go, they should be wired 'fail safe', that is if the estop wiring was to go open circuit, the machine should shut down. In practice, if the inspector hits the estop and it works, you're good.
