It is under the dash, on the driver side.
In a 1987 it's under the steering column, to the left. Hope it's the same for the 1988.
Either under the bonnet OR in the boot ;)

My owner's manual for my 1988 Grand Wagoneer has a diagram that shows the cigareete lighter fuse to be a 10 amp fuse located 1 tier up from the bottom of the fuse box on the left hand corner. It is apparently the same fuse as for the radio.
It is located on the inside of the firewall, left of the steering column. It is way up and hard to see and get to, but it is there!
underneath the steering wheel where the fuse box is.
The fuse box on the 87 Wrangler is located on the driver side under the dash WAY UP top by the windshield
Inside the HVAC box inside the dash.
The 2006 Jeep Commander does not have an interior box. The fuse box in the engine compartment is the only fuse box.
The fuse box is under the hood on a 2008 Jeep Grand Cherokee.
