What is this?
That light grey bar attached to the black thing with the black wire running to it on the EDIS unit?
whatever it is it ain't plugged in and I can't find a plug for it - has to be a use for it somewhere otherwise it wouldn't be on the truck right??

That's a radio ignition interference capacitor. Apparanty, RF noise is generated by the secondary side of the ignition and radiated into the air, which can mess not only with radio reception, but other auto electronic systems as well. For example, if your truck has PATS then it uses a special programmable key which has a transponder embedded in its head. The transponder contains radio frequency generating electronics which signal must be identified by the PATS module in order for the vehicle to start. This signal is transmitted to the PATS module via the transceiver which is a device mounted in the steering column around the ignitionlock assembly. RF noise might interfere or distort the PATS signal, causing a stall and/or "no start" condition.

So why wouldn't it be plugged in? Simply because I don't run PATS or other nifty gizmos? My assumption is that it should be plugged into ground, and there IS a connector on it. It's not like its a generic plug, it has a clip style plug adapter on it with exposed wire
