no your a/c hoses and such should be different. the hose from the water pump should go to your heater core if im not mistaken. if you look at the diagrams there should be 2 sets of hose attachments on your firewall. 1 on the right which is a/c and the 1 set just to the left of them which should go to your heater core. you dont have to eliminate the heat function of your car to eliminate a/c. this way if temps get a lil colder you can still turn the heat up.

niether its a factory service manual or fsm they are year specific for your car unlike haynes and chiltons which covers 84-96. the fsm has alot more info then a haynes or chilton book by far. i also got the suplemental electrical troubleshooting book. they can generally be found on ebay pretty regularly for $60-$80 or so. keep your eyes peeled on the f/s section here as one might pop up from time to time as well. if you look in ebay they usually have a pic of the book which should look like mine below. (might be different color but still the same book)

That is the FSM I keep preaching for everyone to buy. The link is to Helm Inc, where you can buy your very own, brand new, manual.

In your first picture the circled connection to the water pump clearly shows in scooter18155's second scan. The question mark in your first pic is a trans cooler line that connect to the radiator.

The circled item in the second pic also shows in scooter18155's same second heater connections scan. The question mark is over the PCV system inlet hose. From the right valve cover, it connects to the PCV filter in the air cleaner housing base.

RACE ON!!!
