Finally get to the point where I need to ask some questions about wiring...This is my first wiring job in my existence...I got 2F 77 40...... I just can't figure out where to get ACC power,key on power,constant power for the unit....I believe from fuse block???which wire(color) I need to splice?How and where to connect into tail light circuit from DIM terminal on DD computer and from Brake terminal on DD I need to connect to the brake light switch-where exactly??where is the best way to ground the DD computer?After disconnecting of ammeter from original cluster-do I need to connect + and - together or what to do with the AMMeter wires?From Tach terminal on DD should I just connect to the negative side of coil or I need to go fused through the fuseblock??Thanks to everybody who is willing to help...Mike
