iight well spendin a hole lot of time reading wire diagrams and trustin my self ima be installing it my self but i had one question....the diagram msd gave me shows one main ground but there is about 4 other wires that ned to be grounded .now my question is can i ground these all at the same point or do they all need there own ground points?hounestly the diagram is very strait forword but the ground and the mounting point of the modual are my only probs

[ciscoscivic]

sometimes when mounting the others to the main ground, causes issues. put the main ground onto the battery neg, put the others to a regular ground point.

iight i know i have a lot of ??? on the subject but i realy dont wanna mess dis up..wats the best way to create my own ground points?u know wat ima just explain the whole thing..diagram says...BLACK to ground(wich ima put to neg side of batery)...TWOSTEP to ground(guessing needs its own point)..ignition interupt wire(another ground wire)then theres one more wich on the diagram is the main ground and that comes right out of the modual harness...but i allso have two tach adapters wich one has just a black ground wire then the secound has a black ground and one more coming out of its harness...this is wat i meen wen i say im a lil confused about grounding..lol

the main box ground to b-, main ground out of the module to b-, 2step ground to the body or engine ground, the interupt and tach adapter ground can also go to a body ground.
