Is the truck an automatic? Then you probably need to add/connect the neutral drive switch.
But in reality, you can ignore the code. It won't harm anything. Most vehicles don't even trigger a CEL for something like that. That input is only used to determine when to raise the idle 100 rpm or so when the transmission is in gear or the A/C is on.
Alternatively, you could just jumper the connection so that it detects continuity in the circuit when expected.

I assume this is pre '95/EEC-IV/OBD-1. 95% of the time, a KOEO 67 indicates that you performed the KOEO test with the transmission in gear. The computer expects to see the transmission in N during the test. Repeat the KOEO test, being sure the transmission is in N. If you still get a KOEO 67, then go over the neutral position switch circuit to make sure there are no problems.
In saying that, that applies to Ranger based vehicles that I'm familiar with. I don't know what applications use a KOEO 67 to refer to the AC system, but I expect it's a similar scenario. We'd have to know what you're working on.
