I have an 87 D-100 Ram Truck and the connector for the A/C, Heater vacuum hoses disintegrated. Now I have all the vacuum lines laying loose under the dash. The harness comming out of the A/C control is not color coded to match the hoses under the dash. Dodge also does not have the lower harness and could not provide a schematic so I will have to improvise. Can anyone direct to a A/c Schematic?

Try this...
Also the guy at Dodge may be too lazy to look up the correct part for you..the Mopar part# is 3847622
I still see some in dealer inventory across the US.

Thanks very much for the schematic. I will use this and try a different more motivated parts dealer!

A different Dodge parts guy did find the part mentioned in your post (thanks again) and it is the harness which plugs into the AC/heater control unit and then the vacuum hoses referred in your schematic plug into the other end of the harness. My problem is the plug which all the colored vacuum lines from under the dash has disintegrated. The harness is still intact and in good shape. The parts guy said that no part is available to replace the under dash vacuum lines and plug ( what I called the lower harness). Just wanted to see if that matched any information you have access to.
Thanks,

Well for some reason 1987 shows a part# all it's own for that year only...1988 I believe has been used sucessfully by another person and they said only 1 hose was too long. It's been a long time since I had this discussion with him so I'm just rattling on for the moment.
4361066 1987 Not available
4361268 1988 Might be available?
