also did mine up 2 weeks back... no real pics for you cause i screwed up with the pics.... all blur as heck.
very similar setup as springfall just a diferent 12v to 5v converter.
1)prepare your materials, preparation is key
-find out what fuses your car uses (you need to know what fuses you use so that you buy the right fuse tap) after figuring that out, buy the right piece.
-find out where the fuses are located so you can work on the car later (preparation is key... dont wana dismantle the right side then find that the fuse box is on the left)
-get the adapter (get one like springfall which comes with the female ends of the usb cabling or like me, get a unit with the cable hooking directly up to the dash cam.
2)solder and run the cables in first (easier to solder everything up together with everything out of the car
-solder the positive end of the adapter/converter to the fuse tap (leave the negative end untouched, this would be the grounds to the car)
-run the cables through wherever you want. strongly suggest you run them through the headliner, down behind the pillars and through the dash... cleaner that way (remove trim that needs to be removed in order to remove the pillar, then starting from the top so that you end up with enough freeplay on top, run the cable down the bare piller
tape it down or wrap it with the other cables, if its loose, it might rattle* then run through dash)
3) the fuse tap itself is peanuts, its acting as the positive line for the dash cam
-just install the fuse tap in the interior 12v can bus fuse socket (refer to your owner's manual/fuse box diagram for which one, of just use a voltmeter and probe around to find which has power with the key turned to on)
(at this point positive line is hooked up)
4) the negative lead is just bolted on to any bolt on the car (even the fusebox bolt works)
5)test BEFORE reinstalling everything!!
*edit.... should also suggest you get 1a output rather than 3a.... but its really not an issue.
'preparation is key... dont wana dismantle the right side then find that the fuse box is on the left'
I did this.. cuz many merc cars fuse box on right side, and mine was left so
1)fuse can be plugged in the wrong side, so do plug in the correct side (i will power on on wrong side but will burn if blown)
2) if no solder, just cut wire longer and both wires tie dead knot on each other, and it will be damm strong.
after just tape with electrical tape and then use those paper masking tape so the electrical dun slip off when hot.
other than that yeah very same in methods.
