clifford g5 750 blackjack not working?

Hello, anyone that can possible help, I have a 94 Nissan Sentra Se-R. Well I wired up the Violet tach wire to the ignition coil GREEN/ YELLOW displayed on diagram. Now note there's only 2 wire's coming out of the coil. A B/R & G/Y. Can anyone verify? Also I wired the brake light BROWN / red (+)12v input to White ignition switch harness 12v constant & BROWN / white brake light output to brake switch circuit RED / Green. Is this correct? I went over it 3x. Help frustrated. Regards,

If you programmed tach you would know if it was correct, also check the switched side of the brake light with a DMM, if I remember Japanese brake switches are permanent so you could have connected your brown /red to the feed and BROWN / white to the switched side after checking without the need for a fuse, re your coil one side is marked + the other - connect to the minus but test. with ign on, NOT engine run, one side will give you 12v+. How could you get this wrong?
