i have an 88 iroc z with a 305 tpi, i was wondering if anyone happend to know the exact location of the heater core under the dash and what the heater core hoses look like and where they connect to? i see afew metal pipes coming out of the fire wall, one looks like a long hose with two fittings on it right above the motor mount and it looks like there's another small one on the fire wall behind the intake manifold. i know there's also fittings for the throttle body and i'm assuming that's part of the system. the previous owner tore down the car and rebuilt every thing and didn't hook the heater core back up, now that it's getting cold i need heat! any help is appreciated, if anyone happens to have a diagram that would awesome. thanks
