Another turbo conversion comes to life

[Todd Phenneger]

I will support both of Huw's statement.  If you need I can go
outside and check my Kh but the the wire that goes to circuit BS
will indeed make your MC/KH fuel pump relay work properly.  I
just spliced mine in.  Works great.
  My overboost FPR Cutoff has NEVER worked on 4ktq conversion
though, and my Fuel Pump runs all the time when the ignition is
on.  I'm curious if you have the same problem after you finish
your conversion.  If you do I want to compare wiring notes.
