Does anyone know of a good resource for what connections are needed on the truck side to keep various things working? I'm specifically concerned with my 1993, but if theres a good listing somewhere that would be excellent. I'm fully prepping my engine side harness prior to going in, and would like to keep the downtime minimal, so knowing what connections I'm looking to make on the truck side ahead of time would save time.

Things I'm aware of in my research thus far:

Oil pressure sensor to keep fuel pump running (and gauge)
coolant temp sensor (gauge)
AC signal wire to bump up idle

etc
