I was thinking more about this.  I do recall using the double relay
base control unit, but I just looked at the 4k Bentley and it looks
like the ECU controlled this on the 4k.  Other 4k owners out there am
I remembering correct?  If so I must have used the 5kt unit when I
built it.  It has been a while so it is hard to remember back that
far.  I don't think the new owner has extra 5k parts to swap out.  I
guess I need to find my 5k manual and check for troubleshooting steps.
