VSS connections to electronic control assy.

Deep into transplant of 2.3 turbo drivetrain into early Mustang.

Two questions concerning, (for the time being):

1) Dk grn/white wire from terminal 3, VSS Dif, to instrument cluster, and

2) Org/yel wire from terminal 6, VSS Dif, to cruise control amp.

We will eventually be able to install instrument cluster components and cruise control facility, but for the time being how important are these connections, concerning the ECC assembly? Can they be eliminated by substitution of electrical resistors? Can they be bypassed by some hook of crook?

Thanks in advance to the electrical gurus of this forum.

The VSS is used mainly for cruse and electronic speedo, and also holds the idle speed up a couple of hundred RPMs untill the vehicle comes to a stop. It has been reported that running without one can cause a random stalling problem when comming to a stop. I've never had a problem, but usually i try to set the idle a little high on my stuff to off set a grumpy cam. Other than a code in EEC memory(29) you should be fine...
