Looking very nice..... isn't that the original chassis colour of the first batch of mono's...and I'm sure you wont mind me reminding you to fix that brake line securing strap on the bottom of the rear hoop. ;-)
John has all the sensors installed (water temp, oil pressure, oil temp and one for a low oil pressure warning light), and has moved the EWP controller to beside the voltage regulator behind the driver's seat. Makes it more accessible than where it was beside the EWP. (no idea why all the pictures have been flipped in the preview).
When you use an EWP in conjunction with the modded OE pump housing like that you cannot use either of the 5/8" hose fittings on the OE pump housing as they are now under EWP pump flow direction and due to impellor removal flow will be reverse of what they were with OE pump.
Arrows on drawing show what hot ( red ) and cooled (blue ) flow directions will try to do with that EWP setup you have there. To correct this the hose's from 5/8" fittings on T/Stat and bottom of header tank need to go down to inlet side of EWP and the two redundant 5/8"fittings on old OE pump blocked off.
There is a further possible trap in using that OE pump housing without the impellor in that the pump housing design tends to favour flow to the 1234 bank before 5678 due to internal design which may lead to uneven temps on each bank, This applies more to that early pump & front cover design rather than later rev rotation pump housings.
