JonM Posted January 22, 2008 Share Posted January 22, 2008 Recently finished a batch of mods to my RT. More to come... but for now I have a solid platform in place for more fancy stuff. To start, Centech fuse panel and a small 4-pol Hella splashproof relay box. One relay is for switching power to the Centech, the other 2 are for lighting. One unused is for the future. The relay panel is mounted under the side of the rear fairing so it doesn't consume any space for tools and future Autocom/audio boxes and wiring. I thought was pretty meticulous about tie wraps and friction tape, trying to make everything look as factory as possible. Instead of drilling into the rear wheel liner, I made a simple sheet metal bracket and painted in black. I picked up the 2 M8 holes in the frame cross member under the rider seat. One of the M8s already has a nut welded to it, I used a locknut on the other. I also used a larger M12 welded nut on the same cross member for grounding the Centech. I tapped into one of the blue/white wires in the 6-pol headlight wire harness to switch the power relay and it works great. Added black motolights and a set of aux brake lights (non-flashing) from Hyperlites. Both are switched by BMW GS-A switches mounted in the RT-P switch assembly. The switches were rediculous expensive, but they look perfectly integrated with the bike and they work exactly like factory parts. I mounted one upside down in order to distinguish the two from one another as well as to make it more uniform to European cars. Also mounted the RT-P oil cooler fan and shroud. Was a little amused that the top of the oil cooler was marked "KTM Austria". I am controlling the fan with a Permacool electric fan thermostat kit I got from Jegs. You can dial in the temp you want the fan to kick on and the probe mounts in between the fins of the oil cooler. You can also add a manual switch on top of that, so you can show off your fancy police fan to your biker buddies on command. Link to comment
BigAdv Posted January 22, 2008 Share Posted January 22, 2008 Nice work. Are you my long lost brother? I just finished doing the same thing on my RT. I like the relay panel, what wire size will it take? And where did you get it? Check out my pics at www.flickr.com/photos/bigadv Earl Link to comment
Kritou Posted January 22, 2008 Share Posted January 22, 2008 Where do you get the RT-P parts? - here in the UK they appear unobtainable Link to comment
drzep Posted January 22, 2008 Share Posted January 22, 2008 Holy big bucks! Looks clean. Link to comment
JonM Posted January 22, 2008 Author Share Posted January 22, 2008 I used 10 gauge wire from battery, to Centech, and for Centech ground. I buy all parts from Chicago BMW. Their service has gotten a whole lot better since December 1st. Link to comment
Don_Eilenberger Posted January 22, 2008 Share Posted January 22, 2008 Jon, VERY nice. I like that you went to the trouble (as I did) to make up a harness of the new wiring using old-fashioned (what BMW uses) friction electrical tape. That looks MUCH nicer than wires going point to point, and is likely to make for a more reliable and troublefree installation. Nice work! Link to comment
Mister Tee Posted January 22, 2008 Share Posted January 22, 2008 Let's say you JUST want to install an RT-P fan. Do you really need an auxiliary fuse block? Does the fan unit itself contain the heat sensor and relay, or does that have to be wired separate? Link to comment

Does the fan unit itself contain the heat sensor and relay, or does that have to be wired separate? RT-P fan is just a shroud and fan motor, no sensors or switches. I bought 3 M6 (maybe M4) screws from BMW. No other parts. I used stainless 1/4-20 screws and speed nuts to hold the shroud to the bike. I assume the RT-P DME controls the fan. The fan draws a good amount of current and I think CAN BUS would see it if you tapped in to one of the circuits on the bike. Separate fuse would be best. Link to comment
JonM Posted January 22, 2008 Author Share Posted January 22, 2008 The PermaCool unit I used is part number 18905. Link to comment
Mister Tee Posted January 22, 2008 Share Posted January 22, 2008 I see. My bike is new, so I'm just projecting ahead. We'll see if idling at lights in 110 degree weather presents a problem. I guess another alternative might be to intercept the engine temperature signal and wire in an analog relay to have an automatic setup. More work than I'd want to do. Link to comment
JonM Posted January 28, 2008 Author Share Posted January 28, 2008 I did get a few messages asking about other part numbers. In case anyone is interested, I used the following: RT-P switches and housing: 61 31 7 689 809 Fog light switch 61 31 7 653 974 Housing, front half 61 31 7 660 446 Housing, back half 61 31 7 653 978 Bracket 65 14 7 651 032 Screw, M3x12, qty 2 07 11 9 906 411 Screw, M4x16, qty 2 46 63 2 313 281 Screw, M5x12, qty 1 I may have the screw quantities wrong. I didn't use OEM BMW screws, I used stock that I had here. But those are the PNs BMW shows. The oil cooler fan is: 17 11 7 656 030 Fan 46 63 7 690 869 Shroud 63 12 7 682 829 Screw, qty 3 I used my own stainless stock for the 2 speed nuts and hardware to attach the shroud to the bike.

butterbutt Posted January 28, 2008 Share Posted January 28, 2008 Thanks for the info John. Everything matched up except for the illuminated switch. I could not find it where I was looking. I did find what seems to be the same switch with different Part # "61 31 2 315 285" for $40.92 each. Bargain. Bruce Link to comment

Are you part of the local BMW Motorcycle club? There is a meeting Sunday February 3rd. Link to comment
butterbutt Posted January 28, 2008 Share Posted January 28, 2008 I noticed that when looking at your post. I can't believe I haven't seen you around since we probably live less than 10 miles apart. Pic of my baby brand new in the rain. Link to comment
butterbutt Posted January 28, 2008 Share Posted January 28, 2008 Are you part of the local BMW Motorcycle club? There is a meeting Sunday February 3rd. I am a member of BMW MOA but not anything local. What's the deal? Is there a website? Link to comment
JonM Posted January 29, 2008 Author Share Posted January 29, 2008 I am a member of BMW MOA but not anything local. What's the deal? Is there a website? http://www.wsbmwr.org/ I just started going a few months ago. They get together on the first Sunday of every month for breakfast and a club meeting, then a short(er) group ride. On the third Sunday of every month, they get together for a longer ~250 mile ride. So far I like it a lot. They do overnights and longer planned rides too, but I haven't gone on any yet. I commute every day it isn't snowing. Link to comment

I think someone mentioned it will fit the newer RTP housing. Just not waterproofed and looks different. Link to comment
