86 F150 302 O2 Sensor

86 F150 - 302. I would like to know if this uses 1 or 2 oxygen sensors and if it is a 1,2,3 wire O2 sensor.

I've put this is a 87 Ranger and all runs fine except when really cold. Then it goes very rich until I let it sit after building up a little heat.. Just noticed the Ranger had a O2 heater but the 86 f150 wiring diagram shows it doesn't. Here's where it gets interesting. I went to the parts shop thinking no problem I'd get the correct year, but the guy brings out a 1 wire o2 sensor???????
(I've had some trouble with this guy before) .

So, if anybody can tell me the setup on their 86 302 I'd be very grateful.

Thanks

Thank you very much, I was 99% sure but when the 'know it all' parts supplier swears otherwise you begin to doubt yourself.

I'm off to kick some butt!!! (and drive 35 mi further to another guy)
