I just wanted to post up a picture for when people ask which wire it is. Well this is the negative side of the coil. It is the wire with the quick splice going into it.(the big blue thing)
Good timing... I haven't had the PLUG for my coil for some time. I just put the coil back on the car. Couldn't remember which which order the wires went to plug them back on.
Thanks for this post. I have been searching and searching to find exactly which wire is the negative side of the coil, and finally I found this thread. I'm trying to hook up my Innovate SSI-4 so I can datalog my AF. Thanks again!
Thanks, my MSD 6al just shot craps and my tach/window switch was hooked up to the MSD box. Now at least I have a working tach and if need be can spray until I find a replacement.
