My ECU and harness...
 
Here are some pics. Is this EVERYTHING needed to get that 13b in my b2200 started and running? I see 1 port on the ECU is open. What goes there? SOmething I need? Let me know. Thx!! :scratch: I think the last plug is where it gets the power from, at least.

You need a LOT more.

All the engine bay sensors and attachments like the coils, AFM, variable resistor, boost sensor and possibly solenoid resistor (depending on year and injectors).

The "missing" plug on the ECU is for the body harness which contains, among other things, power supply to the ECU, signal from the CAS, output to the coils and a few other important connections.

For reference, you will find a complete wiring diagram in the FSM (see FAQ) which will show you what you will find on each harness and where it plugs in.

well shit. now I gotta look for ANOTHER harness. if too much more bullshit comes up i will convert it to the carb'd intake, and pull the distributor off my 12a and drop it in the truck like that. fuckin efi. lol.

You can cut the body harness plug off of an FC then wire it into your truck's harness.

I would get a complete body harness and work from there. They are not a demanded item, you can get them from any part out thread in the for sale section.

you're missing the CAS and coil wires.

if you get the ecu plug end you can wire them up yourself since theres so much extra crap in the dash harness.
