For sure. I agree. Likely a missed detail.

If it was a running conversion, I'll bet a wire(s) not hooked up or
it's connected to the wrong thing, or ........

..... something isn't plugged in or the wrong thing is plugged in.

i.e. I have an "automatic" wiring harness/ECU. There are two TPS
connectors on it. One sends info to the ECU, the other sends info to
the Jetta auto tranny computer. I found that only the connector
to/from TPS and ECU is needed.

Cheers,

Neil.
