hey guys i have a 86 rx7 GXL and the guy before me took off the hoses for the heater. how do i hook up my heater? and where do the hoses go into the fire wall at? thanks

 

The heater core is accessible from underneath the dash on the driver-side. There is a plastic panel covering it. Both the inlet and outlet lines connect via 2 hoses to hardlines going through the firewall. One is above the slave cylinder on the transmission, and the other is near the wiper motor/above the exhaust manifold. The first one I mentioned connects to the rear iron below the oil pressure sender / oil filter via a long formed hose. It's something like $40-60 from Mazda, but it beats running a mile of generic hose behind the engine to prevent kinking.
