G4 Ver1/2 WRX Plug-In Expansion Loom

William Hurt

Recommended Posts

I received my G4 today and read the installation manual to determine the correct wiring for my Link Map sensor, IAT and WB. The manual provides in the wiring details for the Expansion connector. It goes on to state that only use the 'supplied' expansion loom. Was this loom supposed to be included with the ECU or is that something I have to purchase separately? I have checked US distributors websites for this loom but have found nothing.

Hi William,

The wording is a bit confusing, it means use only one supplied by a dealer. It would need to be purchased separately. As the ECU uses the MAP signal only, your easiest option is to use the AFM signal wire on pin 72. It is connected to AnVolt2 and avaoid having to run extra wires to the ECU.
