The only concern is if the power being drawn is too much for the wiring. You have basically doubled the load of the wiring to the one side. I attached a pic of the wiring. Note there is a left and right send from the integrated power module, IPM. If I had to guess, the pin in the module has corroded or is partially broken and is shorting to power.
Honestly, it isn't something I would suggest. Just keep an eye on things. For the first few days, make sure nothing on the wiring seems to be overheating.
