Here, this is from the Corral.

There are 4 wires that need to be run to the MAF, 2 signal wires and 2 power wires. If you do not have a prefabricated harness, you will have to come up with the MAF connector and two pins for the EEC-IV connector. The MAF can have two types of connectors on it, a 4 pin or a 5 pin connector. The pins are marked A B C D (E) on the MAF sensor. The chart below shows what wire needs to be connected to which pin number on the EEC connector:
4 pin 5 pin
MAF EEC-IV MAF EEC-IV
A 37 (power) A 37 (power)
B 40 or 60 (ground) B No connection
C 9 (signal return) C 40 or 60 (ground)
D 50 (signal) D 9 (signal return)
E 50 (signal)
MAP sensor modification
Disconnect the vacuum hose going to the Manifold Absolute Pressure sensor located on the firewall on the upper drivers side. Leave the vacuum port on the sensor open and plug the vacuum line from the engine. Do *not* disconnect the electrical connector from the sensor.
