If you look at your heater hose lines, they run into the cab continuosly. Got a heater control valve for a 97 Ranger truck and installed it. Runs off vaccum lines in the cab and keeps that hot coolant out of the cab whenever the Vent,AC, or Max AC switch is on. Cut both heater hoses, installed the valve. Get the clamps that go from 1-3/4" to 3/4". You don't want the smaller 7/8" clamps, trust me on this HAHA. Ran a 7/32" vacuum line into the cab. Theres a knockout plug near the floor you can route it thru on the passenger side so no drilling required. Cut the RED! vacuum line and Tee-d into it. You cant miss the vacuum lines, just drop your glove box and they are right there on the left.
There's much better writeup on this ( where I got it from ) but for the life of me I can't find it. Need anymore info just lemme know.
Think I have 26 bux in this mod total. No sense in paying someone just to go to the store for me.
