i've got an 96 (same setup as your 97) and i dont' recall having to use a fitting. all i did was disconnect the one tube and it had enough extra lenght to connect it to the other. no need to splice tubes...

 

check your fans and connections

 

You don't need a 'fitting' for a 97.. [only 93-4 need that]
For 95-7 take off the drivers side TB hose and connect it to the 'steam pipe' that goes to the rear of the heads...
That's it..
I go with that it needs to be bled also..
NO WAY the TB bypass is making it run hotter..

So i dont need to connect them then so where do i put the two hoses at then and are there any pictures of this i couldnt find any for what your talking about!

 

Simple connection method.

 

I did it the right way now as the 95-97 are supposed to be done, im not sure but it didnt ever get over 180 now so i believe that was good im not for sure though i only drove it about 20 mins total, but the car should still run the normal temp because the air coming in isnt what is really cooling anything! and at what RPM does the extra 6hp or something kick in i did it just to hope to cool it down but every little bit counts!
