Turbo install: coolant line hookup question?

[Bruce Jackson]

I am installing my turbo (BB DET) parts tomorrow and I have a question
regarding the hookup of the coolant lines.  I will be using the DET
water neck as the source of coolant.  Which coolant line do I tap into
as the return?  There are two to choose from on the firewall that go to
the heater.  Which one should I tap into?  The car is a 92 NX2000.

Thanks in advance,

Bruce Jackson
92 NX2k:  boost tomorrow
99 G20t:  not stock after tomorrow
