Customer Question

my electric trailer brake controller won't work. which relay or fuse sends power to the plug inside the cab that the brake controller plugs into? 2002 f150 with no original brake option.
JA: How many miles are on the car? Has the car been starting normally?
Customer: 222000
JA: What is the model of your '220000 Ford?
Customer: recently it has started weird
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: pulled and checked all of the fuses. do have the relay for the outside light and timer for the light go bad and wouldn't shut off so I pulled the bulbs.
JA: Anything else you think the mechanic should know?
Customer: the controller worked but stopped then I changed the both parts for the trailer to truck hook up. the glow light on the controller won't even light up. also pulled the plug in from the controller to the truck and tested the male points from the truck on a volt meter which indicated no voltage.
