1987 tbi o2 sensor voltage and 3 wire question.

[olllie]

If i where to purchase a 3 wire o2 kit which I need for a ratio gauge.. like this one...

Could I use the same signal wire from the gauges more accurate, heated o2 sensor. To run both my ecm input and the ratio gauge, off of one sensor?

I understand the reading is in millivolts 0-1v and just a sweep, but is the voltage output strong enough for my computer to still go into closed loop early with the heated o2. And run the rich/lean gauge properly.

what should i do? run a 3 wire for my ecm, and a second 3 wire down stream for my gauge.. also is running a heated o2 in a stock location a bad idea, being self heated, not too sure if a high heat location is ok for sensor life.

5.7 no cats, stock exhaust manifolds with dual out

thanks
