I got everything that were in connection with the engine TD pulled out 
of 91 VW Jetta.  So is with the gas engine in 88 VW Jetta.  Then I put 
the 91 Jetta parts and then diesel engine and 5 speed tranny into the 88 
Jetta without much problem.  Yes some struggles I experienced like 
pulling clutch and brake pedal system out and then put it in the other 
car (manual system to replace auto system).  Now it is fine - no 
problem.  My present issue is wiring!  I use alligator clips to turn on 
fuel cut off valve and glow plugs by hooking them on the positive 
terminal of battery.  After several seconds, the TD engine started 
greatly.  I immediately unhooked the glow plug bar wire alligator clip 
off the battery.  I drove the car around and it was ok.  When I turned 
the ignition key off, the engine kept on running,  I popped up the hood 
and unhooked the fuel cut off valve.  The engine stopped.  It happened 
several times as I drove around, going to some shopping areas.  :-)
  Now my issues are with wiring in correct connection with the fuse and 
relay panel.  I pulled a glow plug relay out of the 91 VW Jetta.  I plan 
to just plug wires into the terminals of the relay to connect it to some 
wires under the steering column.  I was at loss of which wires to 
connect the relay, and to thermostat temperature senders and to the 
intake part.  I need a wiring schematic for 91 VW Jetta TD to obtain 
correct information. I have four 1974 to 1992 VW Repair manuals and I 
couldn't find the wiring schematic for 91 VW Jetta TD.  Can someone 
please tell me where to find it? or if someone send me a copy of it, 
I'll appreciate it very much.  Thank you.  Jim
