Thanks a bunch .
I've been working alot lately and haven't got around to doing this, but I will hopefully get this done tomorrow thanks to all you guys.
Little update, got the add a fuse and hooked the two wires up to the sjb and one of them is fine (start wire) but the other (12v with key on and cranking) is not correct. Its powered up with the key on but when I put it in the cranking position it switches off.
The hunt is still on. Going to look for a Haynes manual at my local parts store to see if that will help find it.
