The solution is what I should have done in the first place. I ordered a relay kit that should arrive soon. I bought a 5 prong but will use it as a 4 prong. It will use the ignition switch from the fuel pump circuit since that will draw very little power. Power will come from the distribution circuit behind the battery. Ground from a close source, and then the accessory power wire will run to the heated O2. This will eliminate power draw from the fuel pump circuit.

Hope this helps anyone in the future.
