Terminator X (AF-AFM-937F) Air Conditioning wire write up using factory wiring for 91-93 Mustang.

The following tech article refers to the Holley Terminator X and X Max for Fox Body Mustang air conditioning systems that are performed at the Anderson Ford Motorsport Installation Facility. We have essentially two versions with diagrams to view. The following information covers general steps and procedures done with the factory wiring that is incorporated into the Holley system. If your vehicle was not equipped with air conditioning from the factory some of these steps may be different. Wiring colors confirmed for 91-93 Fox Mustang. For 86-90 model years refer to the other tech article.

Note*

We now offer the Fathead Garage A/C Wiring Kit specifically for 86-93 Fox Body Mustangs for a brand new wiring solution. This removes the need for the factory air conditioning wiring.

One thing we’ve noticed with the Holley Terminator X system for Fox Body Mustangs is that with all the new wiring harnesses it can scare the average consumer who may not be too tech savvy thinking it’s a monumental task to perform. The reality is that the Holley system is about 90% plug and play. The 10% is what seems to be intimidating. 1- The factory wiring to gain functionality of the gauge cluster and 2- Factory air conditioning seem to be the main culprits of this. We are going to start with the assumption you have all of your factory engine and EEC harness removed from the vehicle and show how straight forward the process is for installing the air conditioning wiring back into the car.

The key things to keep an eye on are the connectors for the factory air conditioning relay, accumulator and ground connectors. Most of these connections can be unraveled from the factory harness. You will need to cut/de-pin some of these wires as they ran through factory connectors that are no longer used. You are able to gain a considerable length of wire if you de-pin the wires needed. You can leave the compressor plugged in and remove the connector that is close to the power steering pump.
