If you're going to open the DFP case, which is quite easy since there are only like 8 small screws to take out from the underside, and possibly replace the seq. shifter with a new one...then if you're not too keen on tackling the wiring job as outlined
here...then as an easier alternative, since you will be voiding the DFP warrantly, you may want to check out the Seq. shifter from Frex, as seen
here as this is a direct plug-n-play device...
Though one would have to consider the costs involved of not only purchasing it but any shipping/handling charges as well, it is still a worthy alternative for those of us who are electronically inadequate...
Well, just my $.02 worth of input!
