hello, i need your help, i bought Greddy RPM Gauge for my Vitz 2002 .I brought it to many electrician (7-8)for its installation but could not found a single person who can fix it for me, i think they are afraid as its wiring is different from other gauges (please see attached pics) , kindly help me if you have any idea regarding it or you know any expert person in Karachi who can solve my problem.
Thanks
