It is my DD. Averaging right at 20 mpg.
I just installed a trailer electrical harness that was Plug & Play. Got it off Amazon for $23, and was listed for 89-95 Sidekick, 96-99 Tracker and Sidekick, also newer models. The electrical connector was located behind left tail light, and back about 14" from tail light, taped to the wiring. I removed tape and plugged it in, and wiped an area clean (with paint thinner), removed double side tape sticker and stuck the electrical controller up against the wheel well. Then there is a 2" square grommet where wires went out of body that I slit so I could force the Four Pin Flat Connector out through. Spot tied the wiring to the cross tube, and now I have trailer lights.
