a/c wiring help needed

[Myron F.]

65 roadster with a/c. Please look at the attached picture. It is taken from the passenger side (no glove box). At the bottom of the pic you will see 2 unterminated plugs. Can you tell me what they are? Are they from the standard wiring harness and are just not used. Being the car is not a coupe is one of them a rear blower connection and it's not needed?

Thanks
Myron

Re: a/c wiring help needed

Good question Myron... I have a '66 AC Roadster and both of my plugs are taped together and not used as well. What started out as a project to repair my clock and fix the vacuum leak on the heater switch is turning out to be a dismantling of the entire dash (one of those "gee I'm this far I might as well..." kind of events).

BTW - if you get a chance can you take a picture from that same position (right side) but to the right of the where you are pointing at, I'd like to see how your defroster duct comes together with the heater/ac box

Gary: I hear you regarding the "gee, I am this far". Well if your 2 plugs are not used I feel good. Mine started as I did not have a heater control valve. Then saw that there was no small dia vacuum hose going thru the firewall. Pulled the glove box out and found the big vacuum hose, but no vacuum switch on top of the heater box, also, no small dia hose. I also found that the blower/vent (lower left cable) was wrong. So I took out the kick panels, radio panels, radio, and clock. Clock and radio are now being repaired. Speaker is wrong - wrong impedance so it needs to be replaced. Behind the instrument panel is the small dia hose inlet and the tach drive cable. I need to push both of them thru the fire wall which means I at least need drop the a/c duct on the left side. All for the a/c? More trouble than it's worth? But I mmight as get it all done. I have part of the duct work out, but hopefully the attached pic will help.

Myron

Just a reminder that the tach and speedo cables go thru a 2 hole grommet ( on 4 speed cars see sect M22 A4 ) and ac vacuum lines, oil pressure line and some of the elect harness go thru a separate 4 hole grommet ( see C60 E5)

Re: a/c wiring help needed

yes, thanks. I know that they are separate and wonder which will be more of a challenge.

Re: a/c wiring help needed

Many thanks for the pictures. Clearly mine is in need of a little work, so as long as I'm in there....

Myron -

Those "lonely" connectors are in all dash harnesses, for the heater switch and the heater resistor on non-A/C cars; they are just taped back out of the way on an A/C car, as the added A/C harness handles those functions. The Assembly Manual (section C60, sheet E8) shows that the connectors were to be cut off before taping the unused wires back out of the way, but cutting them off was hardly ever done.

John;
When first noticing those connectors not being cut off I just thought management, like you, decided it was safer not having bare wire ends that could be pulled loose in the future.
Thank you for all the knowledge you bring to this and other sites.
