Finally got the CatEye Velo 7 bicycle computer wired up and running. It replaces my CatEye Padrone which is wireless and was therefore only able to read off of the front wheel due to required proximity to pickup sensor directly below it.
However, my plan to mount the V7 pickup at the rear wheel--in order to get readings when using the bike in the trainer stand--was delayed due to having to splice in about 16" of additional pickup wire because nothing longer was available from the factory.
Which shouldn't have been a big deal given my 12-years experience and certification in automotive electrical systems. However, I discovered that there was a lot of internet chatter about problems with lost functions, special wire used by the factory, etc, etc.
In addition, it's a very small wire gauge which is not available in anything except crappy-looking and very fragile, single-strand bell wire. As in door bell wire.
Due to these concerns, I actually considered taking the wire harness to a local computer shop and asking them to do the splice for me.
However, paying someone based on a rate of $160/hour to modify a $30 bicycle computer hookup wasn't making any sense, so I settled on the smallest gauge black lamp cord I could find, marked one wire of the 18/2 cord so I'd keep the same side of the sensor connected to the computer as it was from the factory, and hacked that sucker in two.
Then uniformly stripped the 8 wire ends--which included the 4 ends on the piece I was slicing in--and installed 4 crimp connectors. Done. And it worked.
So I'm now able to report that, on my second ride today, I did 3.16 miles in 14 minutes and 42 seconds. Not my best time by a long shot, but good enough for an old guy in the 3rd week or so of the outdoor season.
Hope everyone's having a good day...
