I have a 1987 Ramcharger with a 318. 157,000 miles... I have a problem with locating a vacuum line diagram for the heater control box. The connector on the heater controls has broken and there are 7 lines that I have not been able to connect in the right order. The local Dodge dealer was not able to help and none of the manuals I have show any diagram for the heater box. I could also not locate any diagrams for it on the vehical... Can anyone help

Here is where the colored vacuum lines that come from the dash push buttons go:
Looking at the connector with the male ends facing you and the four connections on the bottom. On the bottom row from left to right the numbers are 1 2 3 4; on top rowleft to right 5 6 7

# 1 dark green tees off to gray line for heater hose valve under
hood
# 2 yellow
# 3 light green
# 4 blank
# 5 brown
# 6 violet
# 7red which goes to one way restrictor - on other side of restrictor is black line from engine vacuuum source

They may be the same, won't know til I post tho!!!!

The short vacuum harness should still be available from Dodge under part number 3847622 for about $24.
Here's another diagram.

That's odd.... Both my '85 and '89 use the diagram I posted... I have no violet hoses,and something's really funky about EZ's setup.... That actually works??

Looking at Chumps, Mine looks like his. It worked in my 85 R/C just fine. Still is.Not sure why there different but I have given it to a lot of people with no complaints so far. Actually, I got it from rcc a while back. That is what led me to here trying to find that answer. Stumbled on to the site and found it, saved it in my files and give it out all the time. I looked forever trying to find it and when I did I wasn't gonna let it go. I knew others would need it.
