I could use some help with the wiring on my MSD 6AL -

I have a Blaster coil, MSD dizzy and the MSD8910 tach adaptor -

I've attached a picture of how it hooked up.

Not showing is the MSD 8910 tach adaptor - it only has two wires going to it. A red and a white - the red is spliced into light gauge red wire coming out of the MSD which is hooked to ingintion trigger 12V - the white wire I have connected to the single wire I have running up to my tach but it doesn't work.

I used to have an optical pick-up with a stock 009 dizzy and everything worked fine..since I went to the MSD dizzy I can't get the tach to work.. Any idea's?

Engine runs fine, just can't get a reading off the tach...

Any help would be appreciated. (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

Ive always used the 8920 tach adapter without problems but others on the board have used the 8910 and were able to get it to work with some dinking around, I just replied to a post a few days ago and they had the same problems with the 8910 but a few showed how you can wire it to make it work.
