Can I use MTH Proto Couplers removed from Proto-Sound Upgrade with ERR Cruise Commander?

yes
I had a Weaver with Proto 1 in it and I put in ERR and it had MTH electro couplers
The PS/1 couplers are compatible with the ERR stuff, they have the same impedance characteristics as the Lionel ones. The PS2/3 couplers should not be used with ERR or Lionel electronics, they are much lower impedance and will overload the drivers.
Where can I purchase wires with the proper connector attached?
I need enough for 4 couplers.
My e-mail is in my profileThank you.
I bought the ERR-compatible coupler connector from Batteriesinaflash.com because they sold it with short wires already attached. Thus I didn't have to mess with crimping and inserting pins into the connector.

Maybe time to invest in an inexpensive crimp tool and a few connector pins.

Bought the same tool and JST plugs. Can't imaging doing ERR upgrades without one....
