WHATS UP GUYS
IM NEW TO THE WHOLE IMPORT WORLD SO BARE WITH ME HERE. I BOUGHT A 2000 CIVIC DX FOR 6K WITH A 135,000 MILES(I KNOW I GOT ROBBED BUT I NEEDED A CAR QUICK).AND IT DIDNT COME WITH A TACHOMETER WHICH I THOUGHT WAS KIND OF ODD FOR A 5 SPEED. SO I BOUGHT A EQUUS TAC FROM WHERE I WORK. AND I HAVE HAD SOME TROUBLE TRYING TO HOOK IT UP DIRECTLY TO THE IGNITION SYSTEM. THE TAC CAME WITH TWO DIFFERENT WAYS TO HOOK IT UP. IT CAME WITH A CLAMP THAT YOU CLAMP AROUND ANY SPARK PLUG WIRE. AND IT CAME WITH A GREEN WIRING HARNESS TO HOOK UP DIRECTLY TO THE COIL. SO I TOOK THE EASY ROUTE AND HOOKED UP THE CLAMP HARNESS TO MY NUMBER 3 SPARK PLUG WIRE. AND IVE FOUND THAT THE TAC READS VERY INACCURATELY. AND I TRYED HOOKING IT TO ALL OTHER SPARK PLUG WIRES TO SEE IF IT READ DIFFERENTLY BUT SAME PROBLEM. SOMEONE PLEASE HELP ME OUT. I NEED STEP BUT STEP INSTRUCTIONS TO HOOK MY TAC UP DIRECT TO IGNITION SYSTEM WHETHER IT BE TO THE COIL OR A CERTAIN COLOR OF WIRE I SHOULD SPLICE INTO. HELP!!!!!

That's recommended for the diesels man! Break down and do the coil hook up. Or, if you're feeling really ambitious, find out the dash wiring diagram for an Si or EX for your year and hook the green up to that.
