Hi, this is my first post here. I have a '70 chevy truck, I've been having starting/stalling questions. I'm removing the MSD 6AL ignition and reverting back to HEI 4pin module. Well I've ran into a problem...the MSD 6AL only used the B+, C-, and ground wires coming from the coil. The MSD 6AL did not use the TACH or BAT, now with the 4pin module I need to use the BAT but there is no wire there to connect to. Also the ground wire now has to go into the new connector rather than to the block, right? How do I hook this up correctly? I don't know how, I did not install the MSD ign. to begin with and I don't have a wiring diagram lol. Help me pleeeeease. Thanks! here's a pic of my actual dist./coil
