I have a '70 Challenger 318 with A/C but the temp control valve on the left side of the engine compartment was removed, along with the hoses. I've looked in the service manual and figured the in/out for the hoses but can't tell which way to hook up the control valve. I uploaded a picture to http://www.ronspage.com/heatervalve.html and I'd appreciate it if you know how this is hooked up to visit there and drop me an email on the connections. Thanks in advance!
