Electric connectors needed for 69 CST/10

[dmjlambert]

Hi, I have a 69 CST/10 with 350 SBC, factory A/C (non-working now but I hope to get it working), and a gauge cluster.

I would like to ask if anybody has leftover parts from a wiring harness or access to a salvaged harness, and may be able to provide me some parts? My electric harness is in pretty good condition, except for these 2 parts:
AC Blower motor switch connector (mine is melted)
Connector to compressor (mine is duct-taped)

Also:

Pin 5 of my instrument cluster connector is not occupied. That is the way it was made because I have a gauge cluster. But I would like one of these terminals that has been removed from a cluster connector, or a whole cluster connector. That pin 5 goes to a working TEMP light and I would like make that light work on my truck, using an indicator-light-type temperature sensor installed on the passenger side of the engine.

I would like to ask if anybody knows about the part I am pointing to with the arrow on the AC compressor connector? It looks like perhaps it is a diode. I'm not sure if that was integrated with the old connector or added by somebody for some reason. I don't see it on the wiring diagram.

So, my want-to-buy list is:
AC Blower motor switch connector
Compressor connector
Cluster connector or a terminal removed from a cluster connector

I most likely have what you need, may or may not have the compressor connector but I have the others.

That is correct. It came that way from GM. If I recall correctly mine was wrapped with electrical tape that started on the connector and went just far enough to cover whatever that is since the truck was new.

Thanks very much, that sounds good. I'll PM you to discuss the details.

Thanks for that info. I think I'll take the duct tape off and clean it up and see what I can do about wrapping it properly. I just got a role of that non-adhesive black vinyl tape. That must be a flyback diode to reduce EMF and reduce arcing on the compressor switch.

Pm returned.
