Re: OEM tach w/MSM dist + 6al
OK..according to the URL that Steiner posted, GM TACHs have an inline filter that has to be bypassed.. Any idea where this filter would be physically located?
I have a TIC-TOC in my car and I am thinking of getting an MSD system. My TAC connection consists of a single wire (can't make out the exact color) that goes to the negative side of the coil. I assume I have to disconnected it from the negative of the coil (as per MSD's instruction), remove the inline filter and then use the TAC connection on the side of the MSD unit. (?)
