Default HEI and shift light

Anybody hook up a shift light to 75+ car with HEI? Where is the negative coil? I see a B+ and a C- (I might have those backwards). Is the C- it? As always any help is appreciated?

On HEI you just hook it up to the tach terminal.

4-wires right??? 1 to tach terminal on the hei, 1 to ground-----pick a block grd of your choice, 1 to light----just tap into an existing instrument light wire, and 1 to pwr---use the center of your fusebox...... should have and accessory terminal or two. I just put an autometer cobalt tach w/ shift light in my 76--------real straightforward.....

If you also run a MSD box - you'll have to connect the shift light to the msd box..

Thanks guys I'll just run it to the tach wire. It didn't mention anything like that in the instructions so I was a bit confused.
oregonsharkman hardest part of owning a corvette and doing electrical work to me is finding a ground
No I don't run an MSD box I've always wanted to but I've always heard they don't do much good when you have HEI.
