Apocalypse

Hi,im doing up a Mazda Rx 7 series 4 the car was originally 13b 6 port, Ive replaced old engine with a 13b turbo and a aftermarket computer microtech L10s. gearbox,re upholstered most of the interior + painted my self and added some series 5 Rx 7 parts such as taillights,instrument cluster e.t.c. Thanks from Rx 7.com, i managed to get the series 5 cluster to work,except for the factory turbo gauge i would like to know if theirs a way to hook it up,information would be a great help. Cheers Apocalypse.
