Oil pressure gauge - hotwire harness

jbc, I've got a 6.4 with a Hot Rod harness in my 70 Dart, so sooner or later I'm going to have to deal with this, so please tell me more or post a picture, etc. retroron

I left the ECU sender alone, and plumbed in the stock type to run my factory in dash gauge. But I'm not running an external cooler.
