In my motorhome I had an old Weldex backup system, a B&W camera and a B&W CRT monitor... the monitor was not working anymore, I temporarily used a small 7" LCD monitor using a homemade cable and a yellow RCA plug, but it was time to change the system!
To have 1080p video I could not used the old composite cable AFAIK, so I opted for a wireless camera, I bought a well reviewed one from amazon (link
). I wanted it mounted in the place of the old one.
When I removed the old one, I thought the old camera was screwed there and I had access to the old weldex cable and 6 pins plug, but no... it was mounted on a plexiglass
square and the wire was attached somewhere some feet below and I had access to only a few inches, I cut it flush... I removed all the plexiglass by breaking it and cleaned what I can of the silicone (what you see on the borders here is alien tape
I used to put the cover back for the night).
To reuse the old wire for the 12V, I soldered 3 of them as ground and the 3 others as +12V. I used the soldering station plugged on the generator. Not an easy task.. I soldered the (provided with the new cam) DC plug.
Then I cut a piece of plexiglass
and mount the camera on it, using loctite for the nuts, tuck the wire inside, using some tie-wraps to secure it. I also put a drop of loctite on the antenna nut. I used silicone for the plexiglass on the hole and caulked it.
Put back the cover, I had to dremel it a little bit to open the space, then caulked it.
Inside part, I removed the central console, removed the old CRT monitor. Using the old weldex 6 pins cable I soldered the 3 wires for ground and 3 wires for 12V going to the camera, and made a cable for taking power from accessories to power the new monitor and the camera, adding a main switch. I mounted the monitor on black coroplast
. It works
All in all it took me 5 hours... I'm glad I didn't need to pay some tech $120/h to do all of this...
