If you run an OPMID oil temp gauge, it directs you to pull power from the front blinker relay. So I've been using that source to power my oil temp gauge and air/fuel ratio gauge. I don't see why you can't power the EFIE from there.Somehow I failed to digest the last sentence solidjohnny.
Installing my EFIE I found all the fuses are hot. May I ask nicely, where do you suggest I pick up a switched source from? Inquiring minds want to know!!!
Thanks in advance!!
