I doubt the '91 is a TDI unless it has been swapped, like a 1.6TD 
(indirect injection). If so, both vehicles should be based on the A2 
platform and the swap would be pretty straight forward.  Only issues 
would be adding the pedal for the manual clutch.

put in the 88 Jetta, both A2, will fit fine.

Thank you Roger and Bryan for response to my question.  I stand correct 
re:  TDI  Yes it is not TDI.  It is TD.  I was confused because the guy 
who sold me the 91 car mentioned TDI.  Maybe I misunderstood him.  
Anyway, ... me still learning ... an old dog struggling to learn new 
trick!  I'm 66 and TD thing is just new to me.  Now re: swapping engine 
and other parts around. I just noticed that the exhaust pipe is a bit 
bigger in a TD car than that in a gassy car.  Should they also be 
swapped?   Yes I am aware that the whole idea is a huge job! :-)    Jim

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
