monte70z20 Posted July 29, 2019 Share Posted July 29, 2019 Hope everyone is well and enjoying their rides so far this summer. I just put the dash back in my 70 and I have a few loose ends that I am not sure where they plug into. The radio is missing from the car so I'm thinking that's what they might be for as everything else seems to be plugged in their respective places. Here are some pics of what I'm wondering about. I've tried to show the wiring colour and the plug end for each harness. I'm assuming The black plug with the cut wires is radio and the cut wires were for the speakers. Thanks in advance for any input. Quote Link to comment Share on other sites More sharing options...
Paul Bell Posted July 29, 2019 Share Posted July 29, 2019 The first & second one is for the radio. It's part of a harness that splits to two more plugs. I *think* this pic is for a one speaker car, more speakers adds plugs. This adapter allowed the line worker to easily adapt the radio.

Paul Bell Posted July 29, 2019 Share Posted July 29, 2019 Third picture is the heater connector. Fourth pic, I'd need to see the wire colors. Five & six, heater resistor. If the car has AC, this plug sits unused in the dash. 1 Quote Link to comment Share on other sites More sharing options...
monte70z20 Posted July 29, 2019 Author Share Posted July 29, 2019 Thanks Paul. Very, very helpful Just to clarify, the Third and Fourth are the same harness, Fourth is just showing the plug end of the third picture. If it is a heater connector, do you know where it plugs into? If you can't see the wire colours in the third picture I can clarify later today when I'm back home. Car did have AC so I will just tuck that away.

monte70z20 Posted July 29, 2019 Author Share Posted July 29, 2019 Wire colours are Blue, Yellow, Brown, and a Dark Orange and Light Orange go into same terminal. Quote Link to comment Share on other sites More sharing options...
Paul Bell Posted July 30, 2019 Share Posted July 30, 2019 Third pic heater plug goes to the blower speed switch. 22 minutes ago, monte70z20 said: Wire colours are Blue, Yellow, Brown, and a Dark Orange and Light Orange go into same terminal. This also appears to be the heater blower switch. I'd say one of them is abandoned like the under dash resistor plug when the car got AC added in.

monte70z20 Posted July 30, 2019 Author Share Posted July 30, 2019 Thanks again Paul. I would agree that this switch is abandoned as well if it is for the blower switch. The fan/blower is functioning with the wiring harnesses that are connected to the heater/ac controls. I'll just label them and tuck them under the dash. If they have power going to some of those wires, could I use them later on down the line if I add accessories to the car? Quote Link to comment Share on other sites More sharing options...
