I have a four wire unit on my 1uz, I was wondering if there was a way to rewire both my primary o2 sensors together and run it at my y-pipe (MKIII with 1uz). The reason is because reaching the o2 sensors in the stock location is a major pain the rear.

I'm sure I tie the signal wires together, but I'm worried about the heater circuits
 
Any reason why? I've decided that I'm going to run the O2 sensors off the down pipe, but again I'd rather just run a single one, and another bung for my wideband.
 
Stock ecu, if it were aftermarket, then I'd only worry about the wbo2.

Unfortunately, the AEM doesn't have an NB output, well it does, but it's not recommended by AEM lol.
 
If its a stock system I would keep it as toyota intended. Getting good clean signals is important and toyota know what they are doing. Aftermarket you can get away with alot more. Cheers
