R33 GTST wiring diagram -1994 model

[HeathGTST]

Im looking for a wiring diagram for an R33 GTST standard ECU.

Basicly what we are trying to do is connect a HKS type 1 turbo timer to use the shift light, speedo warning and so forth..

If any one can give me some hints on how to do it or a diagram on which I can work it out from there it would be most appreciated.

Cheers
