Will do.


Also how different is the wiring of a 2003 L engine to the wiring that is in my 97 4.6 will it work or will I need to get a slightly older engine.

 

I should not matter which year of L engine you install. Adapting them to run in your 97 will present the same challenge. The basic engine controls of the L engines haven changed from year to year. The non supercharged engines have seen a few changes through out the model years. For example your 1997 engine uses a coolant temperature sensor. My 2000 4.6 did not.

The sensors that your PCM doesn't have are but the L engine uses are: Second IAT, BAP sensor, in tank fuel pressure sensor. There are also components that are controlled by the PCM that your 97 doesn't have. Bypass solenoid and the Charge air cooler pump.

i have a 97, i had to drill and tap 2 ECT sensors into the front main crossover in the L intake manifold. this is extremely thin metal so you have to be careful.

 

forgive me for the dumb question but what is an ECT sensor

 

Engine Coolant Temp. speaks for itself.

 

sorry I had had a massive brain fart. I kept thinking coolant temp sensor but which one.
