had engine transplant for mk3 supra (NA-T) so the tacho no longer working .had tried to change resisters for the tacho to suit 7mgte requirement, got failed( God knows what happen)got another digital dash, just wondering if anyone had done this before. just want to find out the wiring to get it work. the current analog dash in the car is non ABS, non TEMS, manual,(only basic require). the digital dash is out of later model auto supra which has all the electrical stuff in it (eg: TEMS,ABS,ECT) with loads of wires.
if anyone can give a advise or hint on wirings, that would be great.
