Hi all,

Newb from the UK here. I've not long bought a 92 GMC 6.2 NA motorhome apparently its RHD from the coachbuilder! I'm currently trying to identify a few bits on this truck and have found this floating in the engine bay apparently doing nothing and its driving me a bit mad. Can you guru's help??

Can you tell I haven't used a forum in years? Unsure as to why 6 of the same pics have loaded. To be clear the gizmo I am referring to is the small square looking thing. So far I've king of narrowed it down to an EGR vacuum solenoid of some kind but cannot be sure with all the info floating about in the interweb. It has 2 blade type electrical connectors and 2 vacuum ports.
