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've got an 8910 new in box sitting on the garage floor. Technically, you don't need it. JCD914 helped me install mine and he just took a wire and connected it to the tach output on the MSD box and ran it to the coil... IIRC. I am putting two MSD 6AL boxes and the tach adapter on eBay today unless someone here wants it... Cleaning up the stuff I don't need..

That's how I have ran mine, with both silver and black dot tachs. I seem to recall that the car wouldn't fire with the adapter in, or it would run with no tach. I think I sent the adaptor to Andy for shipping. Waste of money for the adaptor. The only reason I still use it is that I paid for it. When it dies, I plan to run without. Carlos |
