Previous owner has tape on the vac fitting rear of intake going into dash.
90 degree fitting,,two lines,black and red.
The car is a 1987 A.C.
I am guessing the red line is for heater A.C. controls?
Black is for the switch on the fly 4x4 switch?
I would like to make this a single fitting just for the 4x4 switch.
Thanks for the help,,,my head doesnt fit inside the dash,lol!
