I just Installed a MSD 6a WHAT A difference 100% (IMG:style_emoticons/default/aktion035.gif) (IMG:style_emoticons/default/driving.gif) (IMG:style_emoticons/default/biggrin.gif)
Now my tach will not work. I have searched the forum for what I need to do. I have found no real answer some use the MSD adapter 8910 others the 8920. I have a 73 fuel injected 2.0 with pertronix. According to MSD the 914 (mine) the tach wire used to go to the Negative of the bosch coil and it is called a Voltage Trigger and says to use the 8910. I have read others using the 8920 with no problem. below are two diagrams I found. Which is the correct one to use 8920 (IMG:http://i176.photobucket.com/albums/w177/JCD404/tach.jpg) 8910 (IMG:http://i176.photobucket.com/albums/w177/JCD404/tach3.jpg) THANKS I found this on line about the 8920 http://www.msdignition.com/forum/archive/i...php?t-8649.html |

I dont think you need an adapter....
The dizzy tells the BOX when to fire the coil right? Hmm... the only wire coming out of the dizzy to the box is a signal wire..... you should be able to tee into that wire and have a tach pulse (it used to be the wire going to the negative side of the coil before the box was installed) works with my mallory box and dizzy this way Yes.. the white wire in both mallory and MSD 6a boxes is a trigger wire. 1 pulse per plug (the box decides when to do multispark discharge... not the dizzy) Tee into the white wire out of the MSD 6a box |
