Step 1: Tools and Parts
- The back rest $1 (bought from 99cent store)
- Zip ties
- Electrical tape
- A couple computer fans
- scrap wire and cigarette lighter plug in
- Wire Strippers
- Wire snips
The whole build from start to finish took me only 20 mins so its a very easy project.
Step 2: Fan Placement
I placed the two fans between the support part of the back rest that sits against the seat of the car and the mesh part that your back rests on. this spot is perfect because it allows the fans to cool the lower part of the back where swass occurs and the fans arent suffocating for air. To secure the fans to the mesh I just used a black zip ties and went thru the fan's screw holes on the corners and tightened them to the mesh. simple enough right? I tested it after I zip tied it by sitting on against it and I didnt really feel the zip ties.
Next step is to wire it up!
Step 3: Wiring
I took the 2 wire molex plug and matched wire color for wire color on the plug and fans. Black to black and red to red, then just taped up the wires with some electrical tape. As for the cigarette lighter side, I plugged in the molex plug and used the two wires the plug connected to which were yellow and black. With a little common sense there will be no issues here as long as you pay attention. wire color isnt an issue as long as you know whats what.
The cigarette lighter has two black wires so I ohm'd it out to see what wire is positive on the cord. the tip on a cigarette lighter plug is positive so just ohm out the two wires and see what wire is what. After finding this out I cut off the remaining two wires that werent used on the molex plug (red and of the black wires), then I taped the connections with electrical tape.
Now its all wired up, we can test it out before its taken out to the car.
Step 4: Testing and Finalizing
If your fans dont turn on when you have it plugged in, you either didnt have the vehicles ignition on to where the lighter has power or you wired it wrong. Its ok, you had a 50/50 shot right? haha. theres no worrying needed, having it wired wrong poses no issues to the cars electrical systems or the fans themselves. Just switch the wires around and youre good to go! This only took me 20 mins to build and it was worth every second and $1 I spent. Enjoy!
