I found a premade harness that was on a running driving fiero.

it had a 3800 NA manual swap.

what are the differences in the engine harness.

I have a GTP and have worked with 3800 SC's for going on 7+ years. I honestly never paid much attention to the N/A harness...

There are a couple differences in the top end section but I forgot what they were.

I don't want this deal to fall through if I can make the harness work with just soldering a couple extra connections in.

MAP sensor plug is different between the SC and NA motors.

This is the 3800sc MAP sensor plug


This is the 3800na Map sensor plug

As long as the injector connectors are the same then just the MAP or you can use a series III MAP from an SC engine as the connector is the same and the BBV to be added if you want it. Other then that it is the same harness. Dan

obviously running a bbv solenoid is considered a bad idea.

Injectors are different in ~00+ n/a wiring harnesses for future reference.

BBV is another thing I could live with out on my GTP.
I like simplicity

thanks for the injector note.

Selling the harness now though. Engine was sold.

BBV or BBV delete is one argument that may continue on for a long while. Apparently it does provide some benefit in taking the load off the supercharger and engine under certain conditions, ( and can give a small increase in mileage), but I've been running without one for 3 years without any ill effects.
