blocking bad info conspiracy theory paranoid aliens out to get me big brother is watching Could be one of many different possibilities. LOL
the engine idling up and down is from the ac compressor kicking on and off. mine does it too. its from the e fans i guess cause thats when mine started doing it. i cant help you with the relay.
i just cleaned it. it stopped as soon as i shut the heat off but started the second i turned it back on. i pulled out the drive and drove about a block, stopped and turned the heat on and everyhing was fine.
i normally have my phone hooked up to it the radio. ill try turning some stations on. im going to run the truck today with out the AUX. power wire hooked up. if that is the problem im going to have to find somerthing to wrap the wire in. i like how clean it looks without that things hanging across the engine.
If it turns out you see it doesn't continue mayhem on the GEM module relays by disconnecting the new route of the aux. power wire maybe a Faraday shield over the power wire or around the GEM module could solve the interference problem. I found some rolled roof patch at Home Depot, rubberized on one side and aluminum foil on the other. I was going to use it as a cheap Dynamat alternative on my Ranger doors, maybe that would work for a Faraday shield. Some practical reality in my tinfoil hat concept.
