I have a 1996 B2300 and I think I have an engine computer problem.

I went on car-part.com to source a cheap one near me, but get a HUGE list of parts!

:bawling: Huge... list...

So my question is where do I find my current engine computer to see which one I need to replace it with?

Right-hand rear firewall... re. firewall - engine side or inside the cab? Right-hand from inside car, or from outside (driver side/pass side is easier for me to understand).
 
RH/LH is always from the drivers seat.


Look at the firewall, right above the engine. See that big harness plugged into something, thats the computer.
