Ben, the NG uses a 14mm bottom port for the multi-function temp sender, that
feeds the coolant gauge, etc.  The NG uses a dual temp sender, one pin is for
the fuel system, the other for the ignition system, and that has 10mm threads
that fit right in the top.  Thus, you need to likely get yourself a MFTS for
the coolant gauge to make it work, or build a spacer for the bottom to fit the
10mm threads, you could use an old wheel bolt or even oil pan bolt and
drill/tap the center for 10mm.

HTH,
Javad
