I just installed the ijdmtoy kit and will try to find a one way diode to stop the reverse voltage feedback loop that vin17 was talking about, as mine is doing the same as his.
I Just would like to know if the reverse voltage feedback loop will hurt anything until I can add the one way diode?
Update: I picked up one of these
1N4742A and it fixed the issues with the reverse voltage feedback loop and the radio dimming.
