4 cyl conversion question

[stangman11]

Ok i have a 92 notch that i just converted with all 87 GT drivetrain and componenets im at the point when i need to start doing the wiring for the engine. I have the computer and engine harness in the car not all hooked up yet but ive been told i need a speed density harness for the left side of the firewall instead because it used to be a mass air car if anyone can help with this pleaseeee. I need to get this car running and finished

If the PCM is an 87, then yes you will need a SD harness and MAP sensor...along with the correct vac lines. Did you get a complete engine, or have a complete car as a donar? Where did you get the engine and components?

I got the engine computer and harness out of a doner car complete

I need to know if i need any other harness to get this thing to run cause ive been told there is a seperate harness on the drivers side firewall going behind the dash that gives power to the computer and other things.
