ive got on order, vacuum/boost, oil temp, oil pressure.

oil pressure tells u the pressure the oil is being pumped at
vacuum tells you the 'air pressure' in the intake plenum, like where the air gets sucked into the engine, it tells u the pressure its sucking it in(or if boost, the pressure being pushed in)
i think thats the easiest explanation i can give, lol, i know what i mean, but i find it hard to explain into words ... :S

 

Where did you order yours from stevo? ebay?

 

yeah: here: http://cgi.ebay.com.au/ws/eBayISAPI....1184&rd=1&rd=1

i know there not the best brand, but i like the defi style disappearing look, and they should do the job for now.

also, if u getting a zeitronix from RRM, wait and see if we can get an aussie group buy going if we cant find anything similar locally
