I have a few computers laying around and at first I was thinking of just having a computer in the stoker position because there are already wires in place.(Cadence also)

But I would like to have the info as well.

Here's my thought....

I'm planning to put a Vetta C20 in the captains position, and wiring a C10 or C15 in the stokers. The wifey doesn't care about cadence...

I will splice the speed sensor wires together, and only I will have a cadence reading, anybody else done something like this or have any ideas?

Will this at all affect battery life or harm the computers in any way?

Thanks.
