So apparently some rats thought it would be a good idea to nest in my heater control board and chewed through several wires. Does anyone know if wires can be bought individually or if you have to purchase the entire wiring harness. The wires damaged are in the attached photo. If anyone could identify what wires those are that would also be helpful. The wires damaged are the two middle connectors(yellow) and the left connector(brown).

It may be easier just to replace the connector body and the re-crimp, or solder new contacts on the wires assuming the wires have a little extra length.

Those connectors look like standard Molex KK-254 connectors. A new shell can be purchased at DigiKey for 27 cents, see 0022013057 Molex | Connectors, Interconnects | DigiKey
The crimp pins for the wires are 10 cents each and are here: 0008650804 Molex | Connectors, Interconnects | DigiKey

While they do make a fancy crimp tool a pair of needlenose pliers will work in a pinch, especially if you add a little solder to the connection afterwards. The contacts then just push into the connector shell.

But measure the spacing between the connector pins first, if the pins are spaced 0.1” apart then those are KK-254 connectors.

For the brown wire just strip back the ends, solder the ends together after putting a piece of heat shrink tubing over the wire. The cut yellow wire on the four pin connector looks long enough that stripping back the ends and splicing back together with solder and heat shrink should also work.

I hope this helps,

Mark

edit: There‘s usually a wiring diagram on the inside of one of the removable doors on the heater. If not one should be available in an online manual. Hopefully the wire colors would be identified there.
