Turbo Lance oil pressure source

[Flyhighdave]

I am upgrading my engine monitor to a JPI 830 which has oil pressure as one of it's parameters. I'm looking for advise on the best location to tap into to connect the oil pressure sender. The engine is an TIO540 S1AD. The instruction say to mount the sender on the firewall & connect to an appropriate source with a firesleeved hose. There is a bulkhead fitting on the lower left firewall that I believe is where oil pressure is fed to the cockpit gauge. That looks like it may be the spot to put in a tee. Any advise is much appreciated. Thanks!
