Re: Wiring a PECO insulfrog
I don't know what you mean by small, but in general, you should be able to open up the ties and make the connection. However, I find soldering on the bottom of the turnout to be challenging for some. You can solder to the outside sides of the rail.
Note: The new code 83 Peco Unifrog turnouts, which replace their insulfrog and electrofrog turnouts, already have that jumper in place. You can see them on my website at: http://www.wiringfordcc.com/switches_peco.htm#a7
