5ktq temp sensors

[cody at 5000tq.com]

Ok I'm having trouble with a piece of information. Which of the  
numerous coolant temp sensors feeds the ECU the temp signal? Theres  
the MFTS, but that only sensds the ECU the overheat signal. Then  
theres the after-run sensor which is obvious. Then theres the 2 teeny  
sensors - one of top of the coolant neck on the head, the other  
screwed in to the head itself sorta underneath the hydro-pump bracket.

I can't seem to find referances of those two smaller sensors'  
functions. SJM has a photo that referances the one of the coolant neck  
as the "idle temp sensor" but doesn't have any info on where it's  
signal is delivered.

Anybody know?
