HKS turbo timer hardwire to wires under steering wheel

Its a long shot but I need the mapping of the wires underneath the steering wheel to the wiring of the hks unit -apparently mine was hardwired.

For example --

White Wire ------ to ----- red HKS
Chasis ground ----to --- black HKS
braking brake ----- to ----grey HKS

HKS blue?

If you can repair your harness this will work nicely http://www.hksusa.com/products/?id=837&rsku=3949
