Glow plu relay - Ford Forums

Hi Guys,
I have a 2004 6.0 litre that needs a new glow plug relay. Problem is I can't seem to locate where it is on the engine. I heard the r/h valve cover but not there. I had a 7.0 litre before and it was on the manifold easy to get to.
Thanks for any info.

its on the right valve cover it will have a sensor right next to it the relay looks like a small amplifier with a green connector and a black connector

Thanks for the response, I searched all over the rh valve cove and the only item on it was the module( amp looking thing with two cannon plugs). So I took it to the dealer who sold me the new relay and he came out all smart ass like he would show me what I couldn't see. Well he searched as well and then went and got the head diesel man who also was perplexed. They then ran my serial number and discovered that my truck was the second one to be manufactured for Canada and it does not have a relay only uses that module. They were so interested that they took it into the shop and ran a further diagnostic on it and discovered that the module was good but #1 nad 5 injector were faulty and intermitent. I am going to run a couple cans of injector cleaner through it and they have it booked for more tests in two weeks.
Thanks again for the help.
