With a voltmeter, measure the voltage on each injector connection. One should be 12 volts and the other should be more like 0. You will want to tap into the one that is at 0 volts.
My 2 wire on injector connection have 12 volts???
Probably my trouble???
I Have one Hyundai Scoupe with the same engine 1.5 Mitsubishi, and Him also have 12volt on each wire.
