I'm sure there is probably a year split on the 3.8 between 2 pin or 3 pin. I personally have only seen 3 pins, but IIRC Lars used a 2 pin when designing the collar.
Anyway, the 98 PCM will require a 3 pin sensor and your 97 harness is already setup for 3 pin.
Thanks again.
I got fried today. Spent 3.5 hours in a hot Florida junkyard extracting that harness. Here are some suggestions for y'all.
Remove the hood. It gets in the way and is annoying.
As previously stated, remove the center console to reveal the access port above the transmission.
Remove the fan and the tensioner to get to the crank position sensor easier.
If you don't take a cordless sawzall, make sure you have fuel disconnect tool. Moving some of the fuel lines around will help make extraction easier.
The huge square connector over the transmission is almost impossible to fish up into the engine bay. I ended up removing the passenger wheel well cover. This allowed me to pull the connector over the exhaust pipe and then up to the engine compartment. The heater lines will get in the way so they will need to be cut too.
Use pliers and a flathead to gently separate connectors.
The biggest take away, make your life simple by removing components that are in the way instead of going around them because you don't need them. Save your knuckles and your sanity.
I went with the following tools.
Torx set
Phillips + flathead
hammer
pry bar
cordless sawzall
diagonal cutters
nut driver set
metric sockets (shallow) Deep well would have been nice though
metric wrenches
vice grip pliers
box cutter (carpet)
