Air flow meter wiring for ALFA 156?

Many a times the wires get loose from AIR FLOW METER connector or wires gets burnt.For example check the fig below:---
The two of the wires leading to the air flow meter connector had burnt through the sheaf to bare wire (wires Black/White, Grey/Red and Brown/White).


wires to the AFM carries almost certainly current less than 1 amp.

156's dont have air intake temp sensors but relys on the MAF sensor, which has 4 wires.

one pin in 12v, one is gnd, one is the Air Flow signal & the other is a temp signal.

4-wire AFM terminals:
1. air temp signal
2. air flow signal
3. +5V reference
4. ground



For 5 wire connector

oR YOU CAN ALSO TRY UPGRADING YOUR afm UNIT WITH maf SENSOR.
The MAF kit is a nice upgrade for air flow meter engines.
