Ignition power to gauges?

I installed an oil pressure gauge using the oil switch wire and it works fine, but where else is there easy power to grab off? I want to put in an oil temp too. Thanks r3v

The simplest way is to used the switched aux fuse on the front of the main fusebox. The box has a switched and unswitched fuse and is intended to be be used for aftermarket add-ons.
