Hello Everyone, I have a 2007 Cayman that I would like to update the TV and audio systems. The current original systems have the dash Radio / DVD player two TV's (Front and Bedroom) and a fun pile of wires and switch box to control it all. I would like to add support for a Blue Ray Player, a Chromecast and update the Radio for Bluetooth support and other modern features. The current switch box in the front cubby is only RF cables switch and then the sound system amplifier(? I think). Trying to hook up the blue ray and the chromecast via a HDMI -> RCA and then the switch box has been a P.I.T.A. Thinking of redoing the cabinets over the driver area to have a swing down large screen. The old sharp tube unit is lacking compared to the ones at the house. What systems and equipment have others added / used? What rewiring have you done?

Hi Everyone I just wanted to update everyone on this problem. I was able to finally get it working! I was able to get the wiring diagrams from the web and I used a trail version of Adobe Acrobat and lots of scotch tape to enlarge them to 44 x 25. I found that the Left Turn Combo signal had fuses and relay and that it was on a small sub panel. I went back to the front electrical cubby where the large fuse panel was and found that there was another smaller panel that did have fuses and relays for the turn indicators. When I popped the cover off that panel, one of the relays popped out. It was the left signal relay! I popped it back in and tried the blink and it was not blinking (I just passed state inspection this morning so I knew it should be). I went out back and remove the hotwire that someone had put in place prior to me owning it and presto! It was working, directionals and brake combo. Some tech had just jumped in a wire instead of doing some checking! Thanks for all the input and help. Maybe this can help someone else in the future.

I'm not sure on the motorhome, but I know that Chevy Silverado's are known for the electric motors in the gauges to go south. That happened in mine, where the speedo wouldn't go down, just up and then would go up on top of what was already wrong and getting maxed out. They sell the motors for the Chevy's. Wonder if you can do the same here. It does mean taking the gauges apart and soldering to make the replacement.

My parents had my Cayman PDQ before me and they had to have additional support added welded in around the windshield because they had the windshield pop out a couple of times from the frame shifting around. For what ever reason, there is a lot of flexing in the body framing on these things. Luckily they only had to gorilla tape the edges of the windshield to get back home when it happened. It never broke the glass.

Hello Everyone, My 2007 Cayman is having problems with the Trailer Plug and the Left turn / Brake signal. Whom ever wire the added tow light system did a hack job. They hacked in a 4 pin connector and they also ran a wire from the left turn signal to the red wire of the trailer plug. Since the 7 way plug was broken and the 2 foot cable run back to the 6 way plug under the rear end was in sad shape. I decide to replace the plug and the short harness. I got every looking good again, except I found why they hotwired the left turn signal to the red wire. The Left Turn / Brake signal coming from the chassis wiring is not working. Their hotwire allowed the blinker to work, but the brake light is not working. I can't run another hotwire from the brake light because it will fight with the brake signal. I tried to go through the wiring diagrams I got off the internet from Monaco, but I am having a hard time finding the actual trailer collector in them so that I can follow it back to the next point and find where that point is physically on the motor home. I don't mind running a wire from the front back to the plug, but I am not sure where it would tie in. I tried following the existing wire backwards. and Got past the mud flap and went up (and up and up and up). I couldn't see where it went once it got over the frame near the transmission. Has anyone one else run into a similar problem? How did you fix it? Where are the tie in points for the combo signal? I saw there were a couple of relays, but the wiring diagrams did not identify them so that I could locate the physical units. Thanks Alan
