Is my Ford Ranger a Low Voltage System?
YES, The Ford Ranger is a low voltage system. Ford was one of the early adopters for this new “smart technology” Although some vehicles have had the low voltage turned off we still highly recommend running the IGN trigger and BCDC incase it is turned on again during a service.

Assemble the DIY Ford Ranger Harness
In the JTS cable kit is the midi fuse holder with a small red cable. Fit the cable to one end of the fuse holder (small lug) [IMPORTANT: Do not fit the fuse yet] and the red cable on the 7mtr cable run to the other side.
Grab the JTS Midi fuse bracket, this will bolt to the side of the engine bay in front of the battery. Once the bracket is fitted to your Ford Ranger, you can mount the midi fuse holder and connect the positive cable.
Do not fit the earth cable just yet, the earth cable and the fuse will be fitted in the final step with the midi fuse when the system is ready to be commissioned.
As of this publication the IGN fuse location was fuse 28. As vehicles and models can change it is always recommended to test you fuse for IGN only before selecting the fuse location. It is extremely important that you check the fuse as it can change with vehicle updates and model changes. The images within this article are only a guide and vehicle manufacturers can change the position or use of the fuses. Please use a multimeter to check prior to removing.
