I have tried going off of shbox diagram but i just dont see the same as my car

Injuneer

Someone must have changed it, because my 94 matches the 95 factory manual, which is the source of Shoebox's diagram.

What color are your harness wires?

I'm not sure if there change I'm gonna check them in the morning.
because the wires to the maf match, but the prev owners wife cut the wire 2 days before I bought the car
(so he said) but the wires match the yellow fosure,But the green and other color I'm not sure.

ok so i finally scanned my car and the maf came up on the code i think it was 27 so heres my problem

from my MAFS harness i have a green wire and a yellow and blue/yellow wires

now from my wiring harness i have a black/silver stripped,orange/black line and a yellow/silver stripped wire and one random black wire running from my harness looks to be a ground it was concceted to the MAF harness i think the blue/yellow wire

can some one help with all these colors lol

MAF is DTC 48. DTC 27 is for the EGR solenoid.

The MAF sensor has 3 wires. If they don't match Shoebox's diagram, it's impossible to tell you how to hook them up.

This what your harness should look like. Click on the MAF sensor connector (near the bottom, on the right side), and you will get an enlarged view that will show you the correct wiring.
