Idiot book translation please


#1

Manual says, “The seven-wire trailer harness is protected by an in-line fuse. The fuse is near the junction box”



Anyone know exactly where this is located on a 1995 GMC Suburban and what the in-line fuse looks like?



(I’m receiving low voltage at the factory installed trailer harness)


#2

Most fuses are in a block called a fuse block. An inline fuse is in the line, i.e. wire at each end.


#3

At first, it sounds like the junction box is where the trailer wires plug into. So it is at the rear bumper.


#4

If your Burb has an underhood fuse/relay box, (my ‘02 Tahoes’ is sitting by the drivers side front fender) you may see a wire (possibly blue in color) coming out from the box and has a fuse ‘in-line’. In other words, fuse in the line)

Dekare,
Check all the trailer plug wiring for solid and clean, tight connections, especially ground. Check to ensure the in-box fuse has a clean and tight fit. Yours may have two fuses doing the same job.
Over time, corrosion builds up through humidity.
