I bought an 01 RX with a bad motor sight unseen....bad idea. I didn't know the motor was already in pieces in boxes in the back. I have never worked on an RX before but am handy with cars and tools. Long story short I have an 01 vehicle the motor in the back is from an awd 99 RX and the motor I could find to put in is from an 03 Camry. It's in and works after a few days of cussing and digging in boxes for bolts and nuts but I am having a hard time cobbling the final touches together with the proper hoses and such. Everything is done except for 3 hoses. The 2 large hoses coming from under the throttle body (on the bottom one hooked to each butterfly) that hook to the fuel rail and the other I'm not sure and the hose coming off the the thermostat housing. All 3 hoses are the same size and I think I have one crossed with another. All connections are made as far as I can tell and I'm left with the hose connecting to the thermostat housing un connected and unsure where it belongs. Any help would be great. Thanks
