    I'm in the middle of hooking up a tach to my '88, and I ran into a little problem. I know I need to hookup the tach pickup wire to the (-) side of the coil.....but this coil has four wires coming out of it. And they are not labled. /forums/images/graemlins/whistling.gif There are two red wires and two white wires. One of the white wires has a connector on it labled PED. Is this the tach hookup? /forums/images/graemlins/dunno.gif

    One side of the dual connector should hook up to your distributor. The white wire on the other connector is your tach wire. One wire of the connector that doesn't go to the dist is you power wire (red) and the white is the tach.

    Isn't it marked "tach" on the GM HEI, distributor cap?

    If it is an internal cap coil (big cap) HEI then yes it should be marked tach, but it sounds like he has the dual connector external coil on an 88 TBI truck (small cap HEI).
