1994 XJS 4.0 conv.--- local shop replaced all water hoses and now can not find the vacuum hose for the cruise control hook-up !! it would assist me greatly if one of you persons of such great taste (you do own a JAG , afterall) could look under your hood & tell me from whence the vacuum hose eminates from--(yea,yea--i know--from the engine !)but rather specifically from whence it eminates upon the engine end----???? would certainly save a weary old fella a bit of hair extraction via force--- thanks in advance --1BUM
