backflush:HELP ID OF HOSES
 

1993 MAZDA 929 -

Gonna do a backflush with the prestone kit, you need to find heater hoses that extend from firewall to engine ofvehicle. One is the HEATER INLET HOSE which supposed to run from firewall to top of engine. I am having a hard time finding this...lol...rather be sure than cut a wrong hose and screw up something. Can someone direct me to this inlet hose so im sure its the correct one. Any and all info is appreciated.

wish theymade a damn haynes book for this car...grrrrrrrr [:@]
