Ok I've spent some time on this job since taking those pics earlier today. Right now, the relocator plug is fitted to the block, the hoses are fitted to the plug, and I had to pull out the battery, the strut brace, the alarm siren and the HICAS solenoid just to have enough room to work. Tightening the hoses on the plug was a major pain in the butt.
The plug doesn't seem to fit as snugly as any oil filter I've ever fitted. If this thing leaks, I'm sure I'll be inventing new swear words. Cool, I'll take some more pics tomorrow and hopefully finish up.
